While working on the many (many, many) blocks for that quilt, I read your questions about whether there would be a pattern and I thought a lot about my process for making the blocks, how it could be improved upon, and how it could be communicated in a pattern.
Here's what I came up with.
Refrigerator Magnets is pattern for making 72 different text blocks including an uppercase alphabet, a lowercase alphabet, numbers, and simple punctuation. The block patterns include 3", 4" and 5" tall versions of each character - 216 total characters!
You can see in this block detail the 4" tall uppercase "A" and the 4" tall lowercase "a." The two letters were sewn together, with a piece of spacer fabric between them, and then sashed to create the larger "Aa" block.
You can use the pattern to make blocks like these, or combine the blocks in other ways to create words and phrases. Fun!
I can't wait to tell you more about it.
