I found several packages of mixed knitting needles at the Value Village thrift store. I had to buy several of them to make match-ups, but I left with quite a few pairs of regular needles and sets of double-pointed needles for $18. The bamboo needles were a separate purchase.
The regular needles were the big success for now. I’ll be able to adjust the size of what I knit by switching to larger or smaller needles.
The double-pointed needles include some very small ones that will be useful when I am more skilled and take on more delicate work.
