Mindbender Mobius News

Mindbender Mobius crochet class for CGOA conference

I am excited about teaching a class on this special mobius design! It’s one topic of my seven three-hour class topics scheduled for the big Chain Link conference this July (2020) in New Orleans. This crochet conference has been produced every year since 1993 by the Crochet Guild of America. It’s the longest-running national-level conference. (I’m tempted to call it international because over the years many teachers have visited from other countries.)

As we get closer to July I may update this page with discoveries and other news. For example, when I create a Mindbender Mobius Class Resources page. I’ll add a note at the top of this page saying when it was updated last. It’s likely I’d also announce the news in my newsletters, so subscribe (free) if you want to stay in the loop.

Each One is Unique

Each Mindbender Mobius is unique and so is the experience of crocheting it. It’s a true mobius shape and this means it’s crocheted in infinity rounds—picture a figure-8 path. All you do is add a half-twist to the foundation row before joining it into your starting ring. This simple twist introduces features that have fascinated mathematicians for decades. See the newsletter issue I did about it four years ago; I still enjoy reading it.

I’ve made three Mindbenders so far:

Three different Mindbender Mobiuses due to dye method, fiber blend, yarn weight, and crochet hook size
Mindbender Mobiuses from left to right: Bosni-Misti-Moiré (2016), Dragon Bee (2019), Renegade (2019).

What’s So Different About This Mobius?

These Mindbenders don’t look crocheted. I promise zero knitting is involved. It’s 100% crochet with a regular crochet hook, preferably one that is two or three sizes larger than normally used for the yarn you choose.

For the first one on the left I used Misti Alpaca “dyed to the stitch” Hand Paint Sock, a fingering weight yarn. It calls for a 3.25mm or so crochet hook size on the label. I used size 5.5mm. The dyeing method used for it baffled me to no end! This mobius is the test of my theory and proof of my triumph when I finally cracked its true color repeat. I’ll explain what’s going on with this kind of variegated yarn in class. Have a look at this earlier blog post, Hand Dyed Yarn Three Ways about this yarn.

I wanted to try several more things with the first one, and that’s what brings on the mindbending. When colors change quickly in a variegated yarn, like they do in the Misti Alpaca one, slip stitches are fabulous because they take up very little yarn per stitch. Even if you use a big hook. Just look at how slip stitches helped me get the most out every color in the Jempool scarf!

Unlike Jempool though, I couldn’t stack the colors of the Misti yarn unless I crocheted it in the round with no turning. With slip stitches that means Bosnian crochet.

Challenge accepted! I had never tried planned pooling with Bosnian. I knew it would be interesting because it has an innate lean. And what does the lean do if the rounds are figure-8’s? Each round builds on the others on both sides of the foundation. In other words, the foundation (or Round 1) runs down the center of a true mobius. I think of it as its spine.

Mobius Foundation “Spine”

You can disguise/hide the spine, or emphasize it and turn it into a design detail. For this class I found a simple way to make it blend in so well that it’s invisible. (In the projects above you’re seeing mostly planned texture changes in some of the rounds, not the spines.) Look below at a close up of the Dragon Bee and the Renegade mobiuses: it’s quite pronounced in the one on the left; in the Renegade it melts away to nothing. You can’t even feel it.

The foundation round of a true mobius runs down the center and is usually an obvious ridge unless you do something to make it blend in.
Foundation round at the center of Dragon Bee (left) is a pronounced “spine”. It’s hidden in the Renegade Mindbender on the right.

Here’s another mobius oddity to address: if you’ve ever crocheted a true mobius, you know that not only does the foundation run down the center of it, but all the stitches above the foundation face one way, and all of them below the foundation face the other. It depends on the stitch pattern whether it’s obvious or not. (For example, Doris’ Snow Day is a true mobius and you don’t notice the foundation OR whether the fronts or backs of stitches are facing.)

The back of Bosnian crochet looks distinctly different from the front. It really does look like it’s the back. Tunisian crochet is often like this too. So, what to do? I need to crochet the yarn in the round with no turning if I want to play a moiré color pooling game with it. I could omit the mobius twist and make a simple tube shape, but I wouldn’t be able to add increases to shape it at the shoulders. It would throw off the color stacking. (Have a look at Misti Fondant, which I’ll bring to class. The Mindbender inspired it; I found a way to do it in rounds with turning, plus I shaped it without throwing off the colors by using vertical ribbing.)

It turns out inverse slip stitches work great! It wouldn’t be a mindbender without them. Check the close up photos of the spines above: don’t the stitches match each other on both sides of the spine and look symmetrical?

Prepare to Take This Class

Registration will open in early March. The Mindbender Mobius pattern will be available for the first time in class. The class is rated Advanced. A great way to get up to speed for it is to brush up on three skills:

  1. Slip stitch crochet. Try one of my slip stitch patterns. For the simplest first experience, try the Slipster Slackscarf or Eva’s Ribs. I designed the Luckyslips Mitts for students of my Slip Stitch Crochet 101 classes.
  2. Simple planned pooling. After some slip stitch crocheting, try is Jempool. It combines simple slip stitches with simple planned pooling in color stacks. Have a look at my Planned Pooling class resources.
  3. Crochet a true mobius. Doris Chan’s Snow Day would be perfect!

Shamlian Weltie

This warm, richly textured crochet scarf would be a beautiful wintertime gift.

I began the design as a teaching aid — a rib stitch sampler — for Slip Stitch Crochet classes. To illustrate two important types of slip stitch ribbing, I combined them in one sampler swatch and fell in love. I knew I had to make a bigger version to wear. Not knowing how much yarn a scarf size would require, I made the one shown just long enough to overlap comfortably as a neck warmer.

I called this scarf a “Weltie” as a play on the UK term “welting.” (I noticed this term for what Americans call “ribbing” while doing some research on ribbed stitches.) This scarf is welted with both horizontal and vertical ribs. The fluted vertical rib looks like a ruffle in contrast with the horizontal rib. Like ribbing, it’s much stretchier than other kinds of crochet ruffles.

The pattern includes easy information and styling suggestions if you wish to increase the length and/or width. The one shown required less than two skeins.

Skill Level

Experienced. Three different kinds of slip stitches are used in this design, and one of them is advanced and uncommon: an inverse stitch.
The other two slip stitches, slip stitch in the front loop and slip stitch in the back loop, are common and easy, especially if you’ve already crocheted some slip stitch projects. Try Slip Tectonics or Expedient first!

This scarf doubles as a reference guide for combining these two types of ribbings as you go (no cutting & reattaching yarn). After crocheting this Weltie you’ll know how to add each of these two most useful kinds of slip stitch ribbing to other projects.

I have kept the pattern abbreviations to a minimum, and include International English equivalents for American measurements, yarn weights, and stitch terms.

After following this pattern you will know (if you didn’t already):
– How to crochet classic horizontal slip stitch ribbing
– How to crochet a useful & lovely vertical slip stitch ribbing
– How to crochet three kinds of slip stitches and understand their combined textures
– How to use a hook-led stitch gauge
– How to increase with slip stitches using two different methods

Finished Dimensions

Pictured Weltie is 27″ long X 8.25″ wide {69 cm X 21 cm} measured flat (unstretched). Customizing information is included in pattern for widening and lengthening scarf.

Supplies List

  • Crochet Hook: Size K/US10.5/6.5mm hook or size needed for gauge.
  • Size #4 Medium yarn: Brown Sheep Yarn Company Lamb’s Pride Worsted (85% wool, 15% mohair, 190yd/173m per skein), color M-10 Cream, 1.5 skeins.

Substituting a yarn: Choose a wool blend, or wool-textured acrylic #4 medium weight yarn that lists a crochet hook size range from US H/8/5mm-I/9/5.5mm on its label. These yarns may also be referred to as Worsted, Aran, and occasionally “afghan weight.” If you choose a tonal or other type of self-striping yarn, stripes will run lengthwise along the scarf (not across its width).

  • Optional and recommended: 4 or more stitch markers until you can recognize the last slip stitch of each row of both ribbing types.
  • Optional: A button or shawl pin (optional)
