I don't like the sticky residue of any kind on my wood surfaces after I cut out my pieces so I always start with blue painters tape, It comes off pretty easy and i don't find any sticky residue left on my work when i peel off the tape. Over the tape, I put my pattern that I spray glue the back of and stick it right on the tape. The first time I tried to use spray glue, I found the pattern was lifting on some of my closer really small fretwork, so i tried a glue stick. I found that it worked better for me but I found that I needed to be sure I got the purple glue sticks and not the white. The glue sticks were considerably cheaper than the glue sticks too. About six months ago i discovered spray adhesive at Harbor freight by the CRC company. That company is an American manufacture and have been around for a long time and I knew their products to always be good ones and the cost was only about $10 for a very large can. It works really well for me. it keeps the pattern on the tape and when I am finished it comes off easily. I am sold on it, personally. I too had the sawdust collect under the clear packing tape when I used it, so I stopped using it for a long time. Recently, however, I did try it again and I no longer had this problem. I put the clear tape over the pattern that i had applied to the blue painters tape and I had no problem with the sawdust any longer. Make sure the clear tape is pressed down and sealed against the pattern very well. Not sure but maybe I was leaving some wrinkles in my clear tape that trapped the sawdust, before.
I know I am a little windy but i hope this might help someone..
