prewash the fabric- detergent- no fabric softener- or starch or any other chemical additive.
it is easiest to write on the fabrics if you press the shiny side of freezer paper to the back of the fabric- (freezer paper-not wax paper) use micron pigma pens- they do not get the fuzzy edges lots of markers will get- they are acid free- permenent- and come in a variety of colors and point sizes. after the signatures are all done you can heat set- but the ink is permenent as soon as it's dry- there are a number of fabric markers on the market- the micron pens are easy to write with- & like stated earlier- they do not bleed-fuzz around the edges. and a pen will last a long time.
