Fiber content and weight effect how color appears. If you are in doubt as to whether your fabric will accept dye or achieve the color you want, we recommend testing a swatch first.
Before dyeing, remove any visibile stains on the garment. This will help achieve uniform color results when dyeing. Pre-wash item in warm, soapy water. This helps to remove any finishes that may interfere with dye absorption.
Cover work area with plastic table cover and have paper towels handy to protect against any possible spills.
Fill a microwave safe container with very hot water, enough to cover your item (4-8 cups).
If using liquid dye, pour 1/2 cup of well-shaken dye into the container and stir well. If using powder dye, dissolve 1 package of dye in 2 cups of very hot water and stir well. Pour into container and stir well.
Wet item in warm water and squeeze out excess water.
Immerse item into dyebath and gently push down with a spoon so it is completely covered by the dye. Cover container with plastic wrap. If dye-painting or wax-less batik dyeing, wrap fabric in plastic wrap, sealing the outer edges.
Line bottom of the microwave with paper towels to protect against spills. Place container in microwave and set on high for 1-2 minutes. Check after 1 minute to be sure plastic is not melting as the power of microwaves varies. If dyeing nylon, only heat it for 15-30 seconds, and not for longer than 1 minute, as it is very heat sensitive. Watch fabric closely while doing this.
Carefully remove the container from the microwave. The plastic wrap will be hot so wait a few minutes for it to cool.
Remove plastic wrap and remove item from the dye bath.
