VIDEO: HOW TO CARE FOR YOUR SILICONE MOLDThis mat is beautiful! If the mat looks this good, just wait until you see what you can make with it. These ovals are designed with thin mid-sections so your castings look like they are being pulled in motion. Another great feature–just like the other GeoMats–is that the shapes can fit inside each other to create gyroscope-like forms.
