Don't have a clue where this should go, but this looked like as good a place as any. :)
Admin, feel free to move.
Here's how it's done.
My mouse pad measures 7-1/4 X 8-3/4, the images are sized for that.
I used 3M-77 spray contact adhesive to attach the cover to the mouse pad.
If you don't have a blank white mouse pad. You may want to cover your old pad with and blank piece of your old white T shirt. Before you attach your new cover, keeps the bleed thru down.
Iron-on transfer paper for your printer.
Old white T shirt
Follow the instructions for the paper. Remember to reverse the picture so the text is printed backwards
I also cut out a frame ,oversized, from stiff cardboard to surround the image to keep it from distorting when it's cut free from the shirt.
Coat your old mouse pad with the 77, align over the old pad and stick'er down.
Alignment, here's a couple of suggestions.
1.Use double stick tape to attach your old mouse pad to a window. This will produce a dandy shadow outline on the padcover to be attached.
2. Use about 8 streight pins going around the perimature, near the corner's. With the pointie end up. As you let your cover down over the pins let them come through the edges of the image, the pins will guide the cover down.
Once the cover is down press from the center out to the edges.
The transfer has an odd slick finish to it but it doesn't seem to bother the mouse. But what would bother a mouse?
Anyway, injoy.
