Just a general query, what is the block size that you usually work with? When I started to learn to quilt, the instructor was keen to use 12" as the standard sized block and this is the size I use. However, I have noticed that there are quite a number of quilts where it appears the blocks appear much larger than 12" or is it my eyes that are playing tricks on me? Does it actually matter if they are bigger/smaller or is it just preference? Thank you for sharing.
