If you're not confident with knitting with your handspun yet you could always use commercially spun yarn for the main body of the mittens, and then just use your handspun for the flap, this wraps over the top of the main part of the mitten so the sizing isn't quite so important. Lace tends to be quite forgiving of inconsistencies in size as well, the eyelets give the work a lot of flexibility.
If you've made something using HilltopCloud fibre then why not head over to the Ravelry Group. We have a prize draw thread for things made using my fibre, and I'd love to be able to show off more people's work on the blog.
There were 10 comments left in the silk giveaway as of this morning, the random number generator just picked out comment number 10, which is Susan's comment. I'll be in touch to find out an address and get the hankies in the post.
If you didn't win, keep an eye on the shop over the next couple of weeks, I'll be dyeing up some more.
