Glass gifts

Customizing with insignias, emblems logos and crests: These special designs can usually be reduced or enlarged on a copy machine to an appropriate Cling size (5"x5"  is ideal). Or you can encircle the logo on a 10" round blank. Study the design to see how to best "segment" it. Add lines of outlining as necessary to make sure each element of the design has a leaded line where a new color begins.
