Working on different shapes. The triangles definitely have more flexibility to them, but they would have to be small in order for them to work well. If the squares were also smaller, they would be more flexible too. Depending on the dress pattern that I decide to use, I could end up using a combination of both squares and triangles.
Furthermore, the wire loops I used are too messy to use for my final piece, so I will either have to make or buy some jump rings, so they are all identical and not so messy.
