I cut out a circle of craft foam and trimmed it to fit within the small rectangular samples. My boyfriend heated the plastic and sandwiched the craft foam in between. Once it was hard again I attempted cutting it out. I accidentally cut too close to the edge so we had to reheat the Worbla, reattach the cut off part and then cut it out again. We then molded it into a hemisphere by heating it up and shaping it around a tennis ball.
As the pieces were still curved, I had to use the heat gun to flatten them out first. Once they had
cooled I sandwiched the craft foam between the pieces and molded them together with the heat gun. The first time I did this I got air bubbles! I tried to re-mold it but I ruined the Wonderflex. I had used the wrong sides to heat together so it just tore apart. Needless to say that I learned from that mistake and the second time around I had no trouble at all :)
