Ahhhhh. Okay, warning, scaling the pepakura file makes huge jumps in sizes. The second one I printed out ended up being the size of a mascot head. It was huge! So scaling it down and trying to be precise with the measurements. My aquaresin arrived though so I also have to get started on that jewel~
I don't think $10 for tights is too bad but if you really wanted you could probably find some cheaper. I would just be worried if the cheaper ones would be opaque enough. Really just depends on you budget I think.
