Using Silk Film to Shrink Foam
You might know silk film as being a noiseless moisture barrier for inside cushions to keep your foam dry. And it certainly does that job well. But did you also know that you could use it to shrink your foam for easier stuffing inside your cushion cover? We’ll show you how to use silk film to shrink foam in this post.
Using silk film and a vacuum, you can shrink your foam to 70% of its original size. This is especially helpful when your foam is wrapped in a lot of batting and is going to be a snug fit in your cushion cover.
To shrink your foam, wrap the foam in silk film with the film loosely tucked all around. Then insert the hose attachment of your vacuum under the silk film and press it up against the foam. Turn on your vacuum and the suction will remove the air from the foam, compressing the foam and batting. When you turn off the vacuum the foam will remain compressed for a minute or so, giving you plenty of time to insert the assembly into your cushion cover.
Here’s a video that demonstrates the whole process.
