If you’re expecting a simple process with the result being anything similar to commercial squishies, you’re in for a rude awakening.
1. The instructions are only what you find on this page, there’s nothing included, so there’s no instruction on how much pigment can be included before you encounter issues. I wanted an opaque bright pink, and wound up adding way too much pigment such that it didn’t cure very well. For future reference, the liquid pigments you can purchase through S&T aren’t very strong, so any non-sulfur containing dry pigment or stronger silicone pigment would be more effective.
2. On the topic of curing, there’s NO WAY this will cure in 24 hours. Listen to the video and leave it for several days. If you have a dedicated crafting toaster oven, you can accelerate the cure using a low heat, and I absolutely advise it. I was able to get a good cure in about 24 hours at 90-100°F.
3. The final texture of the squishy is VERY STICKY. It’s almost like mucus. When done right, it doesn’t leave any residue at all, though. It’s just more like those old “sticky hands” from the 90s rather than a mochi squishy of today.
All in all, there’s basically no alternatives for a “real” DIY squishy, and it DOES work with a little trial and error, just be prepared for the learning curve.
