BOM : My quilting guild has a BOM each month. You bring in as many blocks as you would like and for each block you get to put your name in the drawing. I have 3 blocks and 3 chances to win about 12 of these made by other members along with a pattern using these blocks somewhere in it.
Each block is 8 and 1/2 inches. The black squares are 2 and a 1/2 inches. The others are 2 and 1/2, 4 and 1/2 inches and 6 and 1/2 inches. All made from odds and ends of colors, some of which were in the scrap bag.
Then I made one for myself to add to a collection of 8 and 1/2 inch BOM blocks ( all fo 3) But these are made with my Kansas Troubles stash.
