When I did Tim Holtz' Christmas tag day 1, 2010, I did not have the sheet, so I used the 1/2 inch red tape. Boy, when the sheet came, I did another house and what a time saver! If you can get the sheets, it's a much easier way to go. The tape worked just fine, but it was more time consuming.
I bought these sheets to use in making mini albums. I use it on the spine, and have used it with Tyvex and it worked great. It's sometimes a lot quicker to use these rather than doing row after row. I've seen many crafters on U tube and decided to try it and I love it. Very strong!!
