As to prewashing…….. yes/no
Last year, all the fabrics were prewashed, I always prewash. One of the fabrics, I actually had to piece some pieces. If it hadn’t been prewashed, it would have been enough. The shedded edge, straightening cutting edges…. Even 1/4 inch waste was too much.
This year, ordered extra fabric. But 1, ordered all they had. And I have plans for finished project to be rectangle, not square. Borders can add size to twin. So most will be prewashed. But not that 1. And thinking to be cautious with clues that call for it.
