The forearm pieces seemed absolutely HUGE compared to my forearms. I was worried that I'd need to form new return edges, and do all kind of ridiculous things to make them fit. I was not looking forward to that.

The forearm cover strips are supposed to be 15mm, so I cut strips of painter's tape at 7mm. Yeah, I got rid of half a mm. I live dangerously. Actually, half of me thought cutting out a mm (1/2 on each side) was going to help the fit. The other half thought I would end up accidentally adding in that half a milimeter anyway. We shall see!

One section doesn't have a return edge. I only have two hands, so I couldn't take pictures of this in the process! I taped the side with two return edges, and the wrapped it around my arm. I lined up the section opposite the no return edge bit (the far left and far right parts in the picture below) I made marks where I wanted the edges to meet. I was able to reach inside and mark a line by tracing along the other edge. It actually seemed like there was a hint of a line from the mold there, too!



After trimming, I think they're still fairly symmetrical.
