Re: Questions about etching
You can get the glass etching cream at Joanne's or Michael's. It's called Armour Etch and it comes in a purple and white bottle. They also make an array of other glass etching items, including different sized mirrors, glass cutting equipment, stencils, and lettering.
The etching cream washes off easily with warm water, and you only have leave it on for about a minute. It's a very easy, quick gift to make.
It's also dishwasher safe once on the glass.
Hope this helps.
On another note, Dover Books has an amazing collection of books full of graphics, and clipart. These are very easy to copy and transfer onto contact paper and make your own glass etching stencils.
