What is the absolute best foam for a slow-rise squishy?

Most experts agree that high-density memory foam is the best choice for achieving that classic slow-rise effect. It provides the most resistance and takes the longest to return to its original shape, which is exactly what squishy fans look for in a butter-style toy.

Can I use regular kitchen sponges for butter squishies?

While you can use them, they are generally not considered the Best Foam Materials for Butter Squishy Crafts. Kitchen sponges have large pores and bounce back almost instantly. They lack the "creamy" and dense texture required for a true butter squishy experience.

How do I make my foam squishy rise slower?

The best way to slow down the rise is to coat the foam in a flexible layer of puffy paint or fabric glue. This creates a barrier that limits how fast air can re-enter the foam. You can also mix a small amount of silicone into your paint for an even slower effect.

Is it safe to cut memory foam?

Yes, it is safe to cut memory foam, but it can produce small particles. It is best to work in a clean area and perhaps wear a simple dust mask if you are doing a lot of sanding. Always use sharp tools to prevent the foam from tearing or fraying while you work.

Where can I buy the best foam materials?

You can find the Best Foam Materials for Butter Squishy Crafts at craft stores, upholstery shops, or even by repurposing new memory foam pillows from department stores. Online retailers also sell "squishy foam" blocks specifically designed for this hobby.
