Fun project and the result is very beautiful although it is a lot of work for something that won't last. I did not enjoy the ironing part, I made my designs too intricate and they were very difficult to unfold, flatten and tape to the windows. My advice is to truly stick to large shapes with a lot of paper. I used coffee filters, I don't know if the other type of paper would give a more rigid result.

Enjoying the decor on my windows right now!

Such a fun and interesting holiday winter theme.
