I managed to get 4 blocks sewn together yesterday, one 14" and three 10.5".
Here is how they work together. Three 7" blocks = two 10.5" blocks. Four 10.5" blocks = three 14" blocks. This is like a modular quilt and these are all multiples of 3.5". I love math, sorry if I lost some of you. I don't have a clue how I'm going to put this together yet. If I knew that I would be bored with it and wouldn't want to finish it. As it is, there are more blocks to be made and fun playing on the design wall.
I'm assuming I can call this my Valentine cactus now. I think this plant bloomed already in December. I have a bud on a white one and a pink one and they have already bloomed before too. There are 4 plants that haven't bloomed yet. I'm still hoping.....
