I have an angel doll on my patterns page
I also have a snake pattern on my blog, but I haven't fully proofed it yet, so it's only on my blog, not on the patterns page yet.
I think these little gnomes are adorable, and only take tiny bits of yarn.
Garn studios has several free patterns in their accessories collection that take a 50 gram skein of yarn or less.
Here are three:
alpaca wrist warmers
picot edge wrist warmers
I like to use left over washable yarn to make baby socks. Always good to have on hand when someone announces a new baby.
There are several charities that have calls out at the moment for squares for afghans. It's a great way to try a new stitch pattern.
The patterns aren't free, but Jean Greenhowe has many great animal and doll patterns that use small amounts of yarn. The T-rex pattern only used a small amount of yarn, but kids love it!
