I've been doing block of the week with each block the name of a book in the bible. We are up to block 29-Joel. It's very similar to a farmer's wife or dear Jane sampler quilt.
My suggestion is to precut several of your blocks at home, take the pieces with you and do the sewing. Really after 29 blocks, there is no common size strip for the blocks. Each block finishes the same size, but the fabric cuts for each has been different.
