I have seen a couple of videos on You Tube using a product called Glistening Snow Writer by Deco Art. I have some but haven't used it yet, I am planning to use in on my Christmas cards this year (I hope). I got it at my local scrapbook store a couple of years ago for a different project and ended up not using it.
I used stuff called Liquid Applique. You squeeze it on like a glue pen, heat it with your heat tool (be careful because it can get a toasted marshmallow look if it gets too hot) and it puffs up. Pretty cool.
I was also going to suggest flowersoft if you wanted that flaky, powdery snow look. It's easy too. Just smear some glue on, pour some flowersoft on, shake/tap off the excess and press it down into the glue.
I've used both and liked both. I didn't post pics of those projects or I'd show you.
good ideas! About 4 years ago I made these clear acrylic albums that i USED and I bought the flocking that i got at Joanns years ago but it worked really good. I betcha that Inkado stuff would really work out good!!
