Ive got all 5 of the lst block cut and sewn with end pieces..now to try to get them made into a "block"...Im so use to working with 12 1/2" blocks that getting use to these larger strips is a little confusing. I agree with Jaba..labeling the strips helps. Had to dig thru my supplies to find a white marking pencil for the black and dark grey fabrics. Im interested to see how you use blues, yellows and purples with the blocks.. Would you still use the light grey and dark grey too? PLEASE post whenever you all get yours done!!
