Yarn. I started out like most knitters and crocheters, grabbing stuff on sale from Joann (RIP) and using affordable tools. Then I discovered boutique yarns and had a hard time going back to anything acrylic.
Of course, fancy yarn is expensive, so I rationalized learning to spin my own on a spindle, then acquiring an electric spinning wheel, and it’s like I woke up one day surrounded by hand-dyed fiber braids and raw fleece to wash and comb myself. I’m not an expert at it, but I am past the lumpy yarnfails I started out with.
Have I saved money? Hell no. But I do like spinning yarn, and I have made peace with the craft clutter… mostly. I also have been making forays into weaving after a long hiatus.
Yarn: not even once. 🙈
