ThermoWeb is my favorite tape runner. I love it because you can run the tape fast or slow over your paper and it will always work.(some you can only use at a snails pace to get it to adhere properly.) I also love that you can you run it straight or curvy down your paper, as well.
I have used this runner for the last 5 years and I wouldn't use any other. I love how is curves and turns makes it so easy. I also love that you barely have to touch it to the paper, there is no pushing it down it just glides across.
I love this tape. scrapbook.com always has the best price on it and quick delivery. A very good place to shop for supplies.
