I've finished my two color mystery blocks from Canuck Quilter's Two Colour Mystery. I originally made six blocks, but I really needed eight. The last two blocks were surprisingly difficult. Not sure why. I'm pretty sure I stitched them together the same way as the others. It would have been better if I made them with the rest. They're done now!
These blocks are pretty neat. I've been playing with layouts. So many combinations. I need the quilt to be slightly wider than four blocks. I will either add borders or sashing. Ha! Before I posted this, my mother has selected layout #4. Hmm... I could still do a border or sashing with that.
