Yarn needed

What sometimes happens when I am knitting/weaving/spinning, I hit a snag of one sort or another. Sometimes I need more yarn, sometimes I need more knowledge, sometimes I am just disappointed in how whatever I am working on is turning out. The latter is the worst because then I am torn between just finishing it anyway or permanently abandoning the project. Any suggestions?

Knitting: Finished the socks; can't start another pair until I find some matching yarn in a solid color for the heels and toes. Started an L-Bag, using some of my naturally dyed yarn (walnut, onion skins, henna).
Needle felting: still working on the fairy house.
Spinning: Plied the remnants from the gradient project, just to empty out the bobbins.

Tomorrow I am dropping by Simply Socks to find some yarn for heels and toes. The bag I am weaving is held up because I need more of the dark brown but can't find the ball band with the colorway information. I don't usually throw ball bands away but this one is definitely MIA.
