To be completely fair, I picked up sewing recently as a new special interest and I’m still in the learning phase.
I prefer pure cotton (or linen or other cotton based fabrics like viscose or modal) and then the fabric you choose depends on how thick it needs to be and if it should be elastic (jersey, sweat) or not (eg. standard woven dress shirt fabric, denim, canvas,…). I buy most of my fabric online as I don’t like interacting with people, but going into stores definitely has advantages in that you can touch the fabric.
I only machine sew (unless hand sewing small parts is kinda necessary). My fine motor functions are pretty bad (probably autism related), so I got a cheap standard sewing machine and a used serger from eBay.
So far I’ve made a hoodie, some tops/t-shirts, some underwear ( didn’t come out very well tbh, had not the right fabric) and I’ve changed some store bought jeans and t-shirts to fit me better.
Check out freesewing if you’re interested, there are lots of neurodiverse people on their discord server who can help you and the website can create sewing patterns for your sizes.
Depends what you count. Seconds? Milliseconds? Nanoseconds?
