I'm actually following a pattern--I usually go my own way. This one seems a bit odd, though. While it has instructions on how to make the blocks, putting it together feels very random. Lots of "using various combinations" type of directions--no Fabric A, Fabric B, ... I guess this allows for creativity, but I thought a pattern would be more structured, somehow.
I think it will look good--every picture of a YBR I've seen does--it is just different than I expected.
