I knit socks for my family and knit a "little sock" to match to go on the Christmas tree.
That is a cute idea to make the mini socks. I've crocheted a couple pair of adult socks and have yarn left over. Making a mini one to go with the gift to put on the tree is a wonderful way to use up that little bit of yarn. I could even decorate them with a little glitter glue.
I would like to crochet the light strand and send them to my young adult kids to get them in the spirit. Like a care package.
