Because he wants the entire quilt to look like that, I told him he could redesign it so it had HST or I could. He didn't want to do it so I came up with something last night on excel and showed him this morning. He said he'd prefer the original, but liked what I did so I'm going to use my design.
As for the big pieces, which are huge, some of them are at least 15 inches, I told him I'd see what I could do, But it might turn into a scrap quilt with each color block being a bunch of scraps of that color. Either that, or he was going to pay for the fabric :D
