Here is one that I started 15 years ago, and just finished. It has layers of solid blue, black, navy and forest green and red flannel. These are sewn together in more or less straight rows, about 1/2 inch apart. It took a l . o . n . g . time. ( I had to cut some of the rows with embroidery scissors, but now you can use a walking foot and use the edges of the foot to line up with the previous row.)
You cut through the channels, between the seams of just the top 4 out of 5 layers, leaving the fifth layer complete at the bottom as the piece that holds it all together. Square it up, using a Square, or a few quilting rulers.
I bound this one prior to washing it, and found it easier to bind.
I didn't take a photo of the finished product, but my sister-in-law cuddles under it when she is on a Pinterest pinning day! I'll ask her to send a photo, and a sample of her fabulous baking!
