These hats are pretty quick to knit – I started one when I put on a movie with the kids, and finished it later that evening after they went to bed. I’ve been playing with different yarns that I have on hand – single strands, and doubling up to get a marled look. Playing with yarns also means playing with needle size and stitch count, so the “pattern” for these is more of a “recipe”.
It’s not a requirement to participate in the event, but it’s a way for people to participate in something that’s good for the community as a whole. Baby hats are simple to make and don’t take a lot of time (about 2 hrs for me from start to finish), and most knitters will have enough leftover yarn lying about to make a couple. Basically I wanted to give people the opportunity to do something good. I’ll take care of dropping the hats off, they just need to do the knitting.
