I love love love my squares I have them from 2.5 to 15.5 just purchased that one for the bento box swap. Since I bought them slowly and on sale while still not cheap well worth it for me. I am currently working on getting the bloc lock rulers for squaring up hst's I love how they hold the block in place Awhile back my LQS had a moving sale so I got 6.5 and the 4.5 for 60% off. now I'm looking for the most common hst's I use on sale too.
Those blocks are cute Jaba's grand baby is going to have an adorable quilt.
