Hoping to answer some questions about this block. I got a one page direction sheet from a site that is no longer online and I've even lost the sheet--so here goes with some sort of directions for those that have asked.
The Waste Not Want Not Block pictured here is a 8.5 unfinished block. It uses 2.5 inch squares sewn into a four patch with the placement "flipped" as shown. That makes a unit. The next "unit" is a Half Square Triangle unit that measure 4.5 inches when trimmed. I like to use 5 inch squares and then trim. Notice the placement puts the dark at the left side. (This can be flipped for placement into a quilt pattern.) The Buckeye Beauty http://www.quilterscache.com/B/BuckeyeBeautyBlock.html or Jacob's Ladder Block http://www.quilterscache.com/J/JacobsLadderBlock.html is very similar. Most of those are made in a 12.5 inch size and I have made the Buckeye Beauty in many quilts, as in this quilt http://pattilousquilts.blogspot.com/2008/02/call-went-out-this-week-from-bev_24.html but I like the smaller size of this 8.5 inch block. If the dark 2.5 inch blocks are placed so that they string straight through the block, the result will be very different. Also the placement of the HST so that the dark is at each corner makes a difference too. This is a fun block to play with as there are endless possibilities. Isn't that what makes quilting so much fun?
