|There have been several tips posted about using painter's tape. Here's another one.
I've recently been working on a series of muslins while I attempt to refine the fit of a basic blouse pattern. After each round of alterations, I mark them on my pattern and date it. Then I use that pattern to trace out a new one by sliding the old pattern pieces under a new sheet of monster paper so I can start anew with a fresh pattern. To stabilize the old pattern, I use four very small pieces of painter's tape to secure the edges and anchor it to my table. Then I lay the new clean sheet of pattern paper on top of that and anchor it with four pieces of tape.
I find this technique easier than using my home-made weights since the weights can get in the way of markings and if I shift them, they sometimes also shift the paper. The painter's tape does not hurt my table (no sticky gum left behind), nor does it hurt my pattern paper. Sometimes I pull it off the pattern and sometimes I just leave it.
