I read a book by Carol Tuttle called Dressing Your Truth: Discover Your Type of Beauty. To get the author's specific recommendations for dressing according to my type, I went to her Living Your Truth website, took the DYT quiz, created an account, and went through the beginner guide. I went through the beginner guides to all the types, not just mine, and took notes. I wanted to know what she recommends for the other types so I could avoid those things.
I found the content helpful, and considered the ads that came with the content worth enduring. I like thinking about things in categories. I've used the Color Me Beautiful system for my clothes since I was a child, when my mother had a colour party.
I also looked at content online by Molly Bingaman of Ladybird Styling, which is similar to DYT.
I understand now why I have barely worn the Lush cardigan I knitted for myself last year. Its lace design details, unstructured circular yoke, somewhat thick (DK) yarn, negative ease (I did zero ease), and loosely knitted fabric are definitely for a type different than mine.
The sweater quantity of yarn that I bought recently was DK. I returned it. I have not decided what sweater project I will do this fall, if any, but I know any yarn I get in the future for sweaters should be thinner than DK.
You can undo a handknit sweater and knit the yarn into something else. I could do this with my Lush just to be thrifty even though the yarn is too thick.
I understand now why I like the look of wool roving dyed multiple colours but I lose interest after I spin it into barber-pole yarn with the colours all mixed together. No wonder I once spun a repeating multicoloured braid by pulling the sections apart and spinning each colour on its own. In light of my type, it makes sense that I like solid colours, sequential or symmetrical Fibonacci stripes, plain weave, and stockinette stitch.
I expect the information will inform my fibre arts choices going forward. I hope this will mean fewer regrets and more items that work in my wardrobe.
