Some notes about removing tape from patterns.
Use a sharp pointed scratch awl to lift an edge up, then use tweezers or small needle point pliers to pull on the pattern/tape/shelf liner.
Pull towards the center, if there are multiple points to lift, work on each appendige separately, stop at a common area until all appendiges have been lifted. Work from the most fragile to the tougher areas.
Use a very sharp angle to pull across fragile areas about an inch above the piece of possible, minimize the lift stress on the piece.
When I lifted the pattern with shelf liner from the dragon; I started with the tail, pulling the pattern to the body, then lifting the fingers and toes, then the wings from the bottom upwards, and finally peeling the pattern off the body. The tail is 14" long as cut and 1/8" wide at the thinnest. I cut 5 of these and didn't break any removing the pattern.
This is my needle point awl, I got it in a knife set from HF.
