I read this on Penny Halgren site this a.m. & thought I'd pass it on.
"... dicovered that the packaging/wrapping paper around reams of office stationer's normal printer paper has been waxed lightly on the inside, I suppose to protect the product inside.
I cut a section off the wrapping/packaging, ironed it lightly to my test fabric, cut the 2 layers to perfect printer feed-roll size and simply photocopied my hand-drawing on, resulting in a perfect line drawing image for me now to use for my embroidery."
