*What is an OBW?*
I always wash. You may be tight on yardage, but why not add another color (complementary color - something from color wheel etc?) After you sew unwashed fabric you have 3 issues:
1. The sizing on unwashed fabric dulls your rotary blade.
2. When you wash after piecing, dyes may run.
3. When you wash after piecing, fabric may shrink unevenly- puckered or stretched seams possible.
4. Sizing can cause some rash on hands to some. If you give the quilt - baby for example, if you have not washed the fabrics and the new quilt owner doesn't either, the new owner can suffer rash issues - especially kids.
It only takes one quilt with hours of your time to have #2 & #3 above happen - what a nightmare. Nothing worse than having some shrink a little and some a lot - all in the same quilt. Yuck.
