What is Angle of Twist & How to Measure Twist Gauge!

Twist angle in your yarn determines its strength and “feel”. Whether it is loose and soft or tight and wiry. The lower your twist angle, the more loosely twisted your yarn is, and the softer your yarn will feel.

Measuring the angle of twist in your yarn is a wonderful way to ensure consistency in your handspun yarns.

Note that the finer the yarn, the more twists per inch are required to achieve the same angle of twist.

5-10° Soft-Spun
Suitable for articles not subjected to hard wear or abrasion. Low-twist singles.

20° Medium-Spun
Suitable for knitting and can be used plied or as singles. Singles spun at angles higher than 20° would be “energized” and cause skewing in your knitting.

30-35° Hard-Spun
Suitable for clear patterned worsted weaving and embroidery threads. Less palatable to hand knitters.

35-45° Very Hard-Spun
Produces very high tensile strength, suitable for spinning sock yarns.

Angle of Twist

To measure the angle of twist (AoT) in your yarn, place your yarn vertically over the gauge and match up the angle of the spun fibres in your yarn with the gauge. A loupe or magnifying glass may be useful to help you see the individual fibres better. For plied yarns, use the angle created by the ply twist.

Crocheting Granny Squares for the Jethro Cardigan

Image
Crochet Granny Squares are just so much fun to make! Just… one… more round… one more square… For today’s Taking Back Friday episode, I talk about the crochet granny squares I have been making at every possible moment for this past month. I’ve recently been inspired by the Jethro cardigan design by Tanis Lavallee from Tanis Fiber Arts. The Jethro cardigan combines both knitting and crochet in one project. You start by crocheting a bunch of classic granny squares, and then join them all together. Then, you pick up for knitting the sleeves and trim. It’s a really fun and easy way to play with colour, especially with making your own palettes and colour combinations. Mini-skein sets work perfectly to allow for fun colour play with these granny squares The goal of making these granny squares is to play with colour, but I didn’t want to go and buy 6 to 10 full skeins of DK-weight yarn in order to get enough of each colour. And so, I feel like the answer here is DK-weight mini-skeins . ...

Joining Crochet Granny Squares – It’s Easier Than I Imagined!

Image
I recently learned how to continuously “join as you go” (JAYG) for crochet granny squares and I LOVE this technique. And so on today’s Taking Back Friday video , I want to share an update on my Jethro Cardigan project and how I joined the granny squares. As I shared in a previous vlog episode , I’ve been making crochet squares out of three different sets of our Superwash DK Party of Five mini-skein sets. I finished making the 36 granny squares needed, which no two are identical. However, after crocheting all of the squares, I was stuck on how to join them together. They simply sat finished in a pile for a couple of weeks. Luckily, Tanis provided resources with her pattern and one of them was for the “Join as You Go” tutorial. It was fantastic. I’m so proud and excited that I’m almost done. I love how it is turning out, and playing with colours has been the most fun part of this project. If you’re interested in making your own Jethro Cardigan, I want to give you some encouragemen...

What is a Diz and Why Do You Need One?

Image
What is a diz, and why do you need one? Together with a good set of hand carders and a flicker, a diz may be one of the cheapest and most useful fibre prep tools you can get. If I had to choose, I would go as far as having a set of hand carders and my set of dizzes as my only fibre tools. They are versatile and extremely compact. What’s a Diz For? After you jump out of a flicker or the “dog brush” (as your first fibre tool), most people acquire a set of hand carders.  Hand carders  are an incredibly handy tool. It allows us to blend colours, as Diana Twiss shows us in the  Colour & Fibre Play  course adding  Spinning Mix-ins  for a textured preparation. Some fibre artists only use them to prep rolags, but what if you want a fibre preparation closer to commercial roving? That’s where the diz comes into play. A diz, as explained by School of SweetGeorgia instructor Kim McKenna in  The Ins & Outs of Diz Design , is a tool used to remove a lengt...
