A couple of years ago I created this card for a challenge. I loved the way the hot glue created dimension and interest. You can check out that post here.
After being asked to be a guest tutorial author for SCS I played around some more with my hot glue gun and came up with a few more ways of creating designs with the glue.
Tip - Try out different ways of working with the glue, using different embossing powders and different combinations of re-inkers on scrap paper.
For the card above I sprinkled gold glitter about 3/4 of the way through heat embossing, unfortunately you can't really see it in this photo (did not have proper lighting for this shot), but it does give a wonderful effect. The art panel on this card was made by the drizzling the glue. When you add the re-inkers the colours tend to stay within the confines of the pattern spaces.
Here are a few more sample panels that have yet to be made into cards.
Supplies: Watercolour paper, hot glue, embossing powder, re-inkers
