My blue and yellow and clear inflatable was the first one I did. I did not go in thinking about what I was going to make, I only tried to match my colors. I ended up cutting a lot of pieces that were small, so I did a lot of work taping and fitting pieces together. I made lots of long rectangular shapes and squares as well as half circles. I tried to keep some of the bag angles from the original bag to make spikes. My first model ended up having air leaks but it was still able to inflate. I noticed how the tightness of me pulling and taping my pieces together in this model made it look like it had a cinched waist. (I was not able to get a photo for this one, but the reflection of it hanging in the sun is very pretty)
For my second model which is the orange black and silver one, I ended up doing similar random cutting but decided to use scotch tape instead and to hide my tape inside the form instead of displaying outside. For some reason after my form began to move from flat to having angles when I added rounded pieces, it became difficult to tape the inside, so especially around the top there is visible tape. This one ended up turning more round. I think it was because I used some bigger pieces and did not make or use any hard edges. Once again this one had some inflating difficulties like the last, but the form still inflated almost all the way.
For my last piece (the one that looks like a cat) I wanted to try another tape I had, which was painters tape. This help my piece together and ended up helping with my air problems. This piece became very symmetrical when I was doing it and I put two rounded shapes on the corners of what I am calling the cats cheeks which allowed my shape to round there. When doing it I did not realize that the top spikes would end up looking like ears, but I think it is a happy accident.
The one thing that I did really struggle with was actually cutting the plastic pieces, I do not know if all my scissors are dull, but I ended up tearing a good amount of plastic because it would not cut.
