A friend asked me if I had tried this method to copy a garment. At first I was pretty skeptical because I have copied garments by taking them apart and by scratching off a pattern from clothing that I did not take apart. Either way there are several steps and accuracy is easier if you have the pieces to lay flat. I was not excited about using tape on a garment I planned to wear again, but 3M's blue painter's tape is made to be less tacky so there is no residue. As it turns out this is probably the easiest way to copy a garment and the bonus is that you can mark your exact seam lines to insure a proper fit. Here is how.
A clean, fresh pressed garment that fits perfectly.
3M blue painter's tape, I used two sizes the slightly less than an inch wide size and the two inch wide size, you could use wider too, just depends on how much space you need to cover, you don't have to have two sizes, but I will explain in the instructions why it is useful.
Tissue paper, tracing paper or other paper to place on the sticky side of the pattern once completed.
