First-time poster, long-time knitter for a4A.
When the youth campaign was announced, I pulled out my go-to sweater pattern, Knitted Seamless Raglan Sweaters, by Leisure Arts. Cast-on, knit, increase here and there, and suddenly there is a sweater. This yarn, Patons Classic Merino, is nothing if not colorful. I hope it keeps a girl or boy warm.
These mittens are made top-down also. The thumb is knit separately and then attached, knitting back and forth, with a k2tog. Eventually you start knitting in the round again. There are not the usual holes at the thumb that I usually get knitting wrist to top.
