Yes and yes. It is easy and super light. I started planning my Christmas layout earlier this year and that's what led me down this path. I wanted something light that I could store easily and perhaps use for a few years. Mission accomplished. The layout is in four quarters any of which I can pick up over my head with one hand. It weighs next to nothing.
You might even try making a practice mountain with the full intention of throwing it out. It's like making pancakes: the first one always looks the worst. After that, you get your technique down and it's easy.
Have you ever used Great Stuff spray foam around the house? I have quite a bit. When I've used it around window and door casings, my primary concern was always making sure I didn't use too much. I was worried about over expansion. What I discovered for this project is it's almost the exact opposite. You want to be pretty liberal with it. Then you give it a few minutes to expand. Then you put the quilt batting on there. Then wait a little more. It seems like when I put the quilt batting on there, it really killed the expansion. After that, I start pushing on it and encouraging it to take the shape I wanted.
And yes, I used only glitter on top of the white paint. No adhesive. When it was dry, I took it out on the lawn and brushed off the excess glitter.
