I finished my clue four this morning.

re: consistent seams, if you ARE consistant, your seams will match across the quilt.
But your items will always be a different size than the pattern.
Where the problems arise? If you are making blocks for a group project. The last guild I belonged to finally started returning wrong sized blocks to the makers. I don't blame them.
Adding borders per the pattern, they won't fit right, so you have guess work combined with a tape measure
Looking forward to clue 5, Sharyn
