I've not yet figured out how many are possible with a 16-piece block. I know it is at least 12, but I'm guessing there might be more than that. Thanks to EQ I have lots of different colorations planned. Now to decide which 6 to use for my blocks.
I've started a new block of the month I purchased several years ago. Each installment came with 3 fat quarters of fabric. Each pattern presents a block with three possible colorations using the three fabrics. Three of each of the blocks makes a nice wall hanging. The patterns go on to challenge the quilter to explore other color arrangements using the same three fabrics. I'm making 6 blocks each month, which will give me a large queen size quilt.
I'm having lots of fun playing with changing colorations. They can really change the look of a block to the point where it is hard to realize it is the same block. I've been finishing six blocks a day, so I should get this top finished quickly.
Playing with blocks is so much fun!
