I bought a Wonderart Latch Hook Rug Kit called 'Snow Wolf'. The wool colour key says there are four types of blue; light blue (symbol is a bold L), spec. blue (symbol is a square), medium blue (symbol is a triangle, and dark blue (syombol is a Z). However, I only have three of them, a light, medium and dark, but I don't know which blue is missing. I tried counting the strands and matching them to how many the pack says there are to determine which colour I don't have, but all the numbers are wrong. I'm guessing I don't have light or spec. blue (stands for special??) but can't be sure. Does anyone have this kit and had the same problem? It's a christmas gift for a friend and needs to be completed soon.
