It is my intention to start putting together some sample blocks, so I can try new techniques and what not. I have no plan as to what I might do with them, which doesn't really help me determine the size.
I've seen a design for setting 3" sample blocks into another block that makes them 6" blocks and pulls the whole thing together, 3" would also be challenging in terms of technique.
I think you could do the same thing with 6" blocks, putting them into host blocks that are 12 inches, but as you need some of the fabrics from the original block for the host block, that starts being a lot of fabric to hang on to, which would be wasted if I never put it all together, I'm less concerned about that with the 3" idea, as it would only be about a quarter the amount. 6" would also be big enough just to go ahead and do something else.
9" or 12" also appeals as I could put a fairly big quilt together with a relatively small number of blocks, 12" might win over 9" as there are more different grids that fit on to that (the same would be true for 6").The worst thing to do would be to start a pile of each size, that would be a recipe for never making a sampler quilt!
Any ideas, what have others done?
