I always try to find a cheaper way to scrap.
I love the embossing looks in layout or even better in a card but the heat tool is darn expensive.
Here is what I did:-
I’m using an oven to melt the embossing powder and it works though you have to be extra careful.
Or you might use an Iron. Yes your iron. Iron on the surface of the embossing powder BUT don’t let the iron touch the powder. (layur)
Good luck! And let me know it these tips help you.
