The original edge was just the fabric from the front folded over the back and whip-stitched. (Sorry, didn't make that very clear). So, I was guessing I would have to remove that folded part and put the new binding over the old edge. For using new fabric, any tricks to get the new fabric "worn" so when they wash the blanket the new doesn't shrink excessively and pull? And my guess here is to wash it and dry it in the dryer multiple times.
