Question about the Disappearing 9 patch???

[kensington]

So, half yard of 9 fabrics will make what size quilt top?

Each half yard will net you 24 charms, so. 9 fabrics xs 24 charms is ... 216 charms, made into 24 of the nine patch, cut into 4 squares, each... 96 of the 7 inch blocks... depending on how you set them a nice twin, with borders, maybe a full size?
