the colors do fade with many washings but it is pretty easy to just (brighten) the colors when needed, you just re-color and re-heat set. for the past 10 + years i have helped a local pre-school make crayola quilts. even the very first ones are still used and great. a couple of the blocks had to be gone over to brighten them, they were quite light to start with. but they do hold up to washings quite well as long as you used pre-washed fabric and heat set the pictures.
