I knit these tiny bags yesterday evening. The green one is Galway Highland Heather worsted weight, knit on size 5 dpns, and the multi-colored one is Koigu Kersti, on size 2 dpns. I used small odd balls of yarn for them, and still had yarn left over when I was done.
The multi-colored is Maggie Luongo’s Amulet Pouch, and the green is Janelle Schlossman’s Knitted Pouch. The patterns are very similiar, and make nice tiny bags — both of these would be filled full if you put a golf ball in them.

A Phileas! One of my favorite pens.
(I love the bags)
I do love my Phileas, and it’s a great reference for size for these little bags.
