I did try them on, and do they ever feel good! Soft, warm, cozy! I hope they fit her well and that she will enjoy them for a long time. They are that good combination of 75% superwash wool and 25% polyamid, a yarn called "Step It Up" from Mary Maxim.
Socks are a good project because they have enough challenges to be interesting, are not so huge that they take a long time to knit, and are generally much appreciated as a gift.
