I made a block for a QOV type project which requested a specific block and a specific size, of course, but they asked that the block be sent un-trimmed. Assuming that must have made it easier for them to trim up the blocks to a usable size. I must say, it was really hard to send them that un-trimmed block. I wanted it to look perfect. I know this isn't exactly what you asked, but thought it kind of fit in here, within an 8th of an inch???
