Why the middle of the quilt fr the block placement ? why not use thse blocks and work around them, with flying geese or 1/2 sq. trangles,or check-board blocks. Just lay the blocks down a little small than you want the quilt to be and use other blocks that have names that mean something to the person that will receive the quilt sort-of tell a story using the blocks you have and ideas from the past that these people have?
