Place each printed fabric sheet separately to dry, rather than stacking them. The inks will still be wet and may smear if you stack the printed sheets on top of one another.
Allow the printed fabric sheets to dry thoroughly. The Bubble Jet Set manufacturer recommends 30 minutes. I've always waited 24 hours.
After each fabric dries, take it off the stabilizer backing. (To reuse your Avery labels, I suggest placing them back onto the backing sheets they came on.)
Rinse each fabric sheet for at least two minutes in either mild detergent or in Bubble Jet Rinse (according to the instructions). Bubble Jet Rinse helps further set the inks onto the fabric and to remove any loose ink. Caution: protect your hands from the chemicals you are rinsing off these fabrics by wearing rubber gloves.
Rinsing in Bubble Jet Rinse:
Here's a tip from Caryl Bryer Fallert's book Quilt Savvy: Fallert's Guide to Images on Fabric. An easy way to rinse in Bubble Jet Rinse is to fill your flat plastic container with water, add the appropriate amount of Bubble Jet Rinse (according to manufacturer instructions) and then run each printed fabric sheet through this solution. Drag each fabric through the solution for two minutes, constantly moving the fabric sheet through the solution. Be careful not to let the fabric fold back onto itself.
It is trickier to wash the fabrics in the washer because of the twisting and wringing that the fabrics go through. You know how everything rubs together in the washer! Performing the initial rinse step in the washing machine increases the chance of fabrics bleeding onto one another before the inks are set. After the initial rinse step, these fabrics are machine washable in a mild detergent.
