Also, you can use liquid watercolors (First Art is one brand) to
dye them. I just put a few drops in a ziploc baggie, add the
noodles, seal the bag and squish around until they are coated.
You may add more drops, bu t be careful because you can make the
noodles too soggy. Then I spread them out on paper towels to
dry for a few days. Store them in a coffee can or something.
The kids love them on their masks, collages, etc.
