For the flannel baby blankets I wanted a simple, fast, binding. I decided to use the backing folded over to the front. I folded the edge twice which results in 4-layers so the edge would be a bit thicker than the blanket. The corners were really thick, so I decided to use a miter for a smoother corner.
How to make mitered corners
Blankets are two layers of flannel. Backing is cut two inches wider.
Fold over one inch and iron.
Fold over again and iron.
Unfold and cut using the fold lines for guides.
Refold first fold on both sides. Fold the newly cut angle down to pressed line.
Refold the sides to previous press lines. Align corner folds.
Then I stitched the corners and edges.
