Oh me too. Im currently slogging my way through all my scraps - although the pile doesn’t seem to be getting any smaller!Wow, these are stunning! You're very talented.
I recently used up almost all my mismatched yarns (was given quite a lot when someone I know died, plus a few random balls I'd bought but didn't love) making a big crocheted basket to keep my knitting and crochet stuff in! It was very fun to do, using 4 or 5 yarns together to make a thick, stiff fabric so that the basket stands up on its own.
I personally get much more of a thrill out of using up what I have rather than buying and hoarding materials. I'm now working on some socks using bamboo yarn, and won't buy any more for another project until I've finished these socks.
Plus, using it all up is a perfect excuse to buy more.
