This adorable owl backpack is an ideal handmade holiday gift.

Pattern lists the following materials:
One 9-inch brown zipper
2 black buttons for eyes
6 yellow buttons for backpack straps
3 balls of brown yarn
1 ball of cream yarn
1 ball of orange yarn
1 ball of antique yellow yarn
Scissors
Yarn needle
Size 10 USA, 6.5 mm 12-inch knitting needles, or a knitting machine
Fabric glue
Brown thread
Sewing machine

The yarn is presumably worsted-weight, but no yardage or ball size is given. As the bag is felted, the yarn needs to be a yarn that will felt, like 100% non-superwash wool; this isn’t stated in the instructions.
