This post is a follow up to an earlier post on How to Make Curves with Copper Tape. The video below shows how to make corners with copper tape. Here are the written directions:
To make a corner, place the tape along a straight line up to the outer edge of the location of your corner. Fold the tape so the adhesive side is on top and the tape is at a 90 degree angle to the tape you have already placed and headed in the opposite direction you want the tape to go. Now fold the tape back on itself headed the direction you want. You should end up with a folded corner. Press any creases flat using a tool with a smooth hard surface. I use a bone folder but the handle of a pair of scissors will do as long as it is smooth.
If that was as clear as the reason the Kylo Ren, the son of Leia Organa and Han Solo, became so evil, check out the video below:
