The mom and pop hardware store here had no idea what painter's tape was. Never heard of it. When I asked about the Frog Shape Tape they acted like I was crazy. I had to pull it up on my phone to show them (no internet in the store ?) Urrg. Give me the big box store anytime.
I have used the Frog decorative edge tape to mark lines. It comes in chevron, wave, and scallop. I use the scallop tape a lot.
