A Disappearing Nine Patch Block
This quilt design was not made using Disappearing Nine Patch blocks; but it was inspired by them.
Nine Patch blocks are cut into quarters and then reassembled to create various quilt patterns. When this is done the Nine Patch blocks disappear.
What if this were done with other blocks?
There are a large number of blocks that, like a Nine Patch block, are designed on a 3x3 grid. A few of these are shown below. What if I make new blocks from each of these. I'll take a quarter of each block and play with it to get a hint of what sort of designs are possible.
These are very easy blocks to design. I think I'll call them Quarter of Nine blocks because of where they come from.
The last time I looked, EQ6 listed 57 blocks that were on a Nine Patch grid. There are, no doubt, many more. You might want to play with some of them and see what kind of Quarter of Nine blocks you can discover.
