|Save the paper part of Wonder Under® to use as a pressing sheet on exposed fusibles you need to iron over.
A larger project using WU is a great time to save it, so you'll have a good sized piece of paper [I saved a 15 inch circle from making a fabric bowl]. Use a permanent marker to write 'wrong side' on the paper before you remove it from the original project, as the glue side of the WU paper is the non-stick side.
When using as a pressing sheet, let it cool before removing project.
If you remove the project before it cools enough, some fusible or glue may be left behind on the paper. This comes off the paper easily by rubbing an old dryer sheet over it...or reheat project, let cool, so glue stays on the project.
I like free stuff!
