I find that the paint samples at Lowe's are a great way to play with color. Go grab a bunch and cut out the chips. Then make combinations that please you and go get yarn to match! The great thing is, they have already put some colors together inside the folders, and I have seen combinations I never would have thought of.
The African flowers are coming along. I can tell I don't have a plan yet, but am just going crazy with the colors. I'm going to be making a purse eventually, but for now, just playing around is too much fun to stop!
