I have a blast yesterday making these. I figured out how to pretty much chain piece each block, and that helped a LOT. :) Fun and easy to make. :)
Here they are, all 15 that I have made so far. I know that the Granny Block tutorial says to put two colors into each block, and you can see that I did that on block 7, yellow (top row all the way to the right) and it looks pretty cook, but the rest of them are pretty much just similar colors together. I also did that one striped one.
