I was gifted a Block of the Month "kit" with all the blocks and finishing fabrics...started to cut it out, and discovered 2 months worth of fabrics did not contain enough of the fabric to even scrimp and get pieces cut...Of course the kit is a couple of years old...so no way to find the fabrics...in one case I need 4 2/12 inch squares...which are prominent in the block..so will have to "wing it" when I get to sewing it.... One of the reasons I hesitate to buy kits!! Sometimes way too much fabric...but the opposite can be true and frustrating!
Good luck with finding the additional fabric you need!
