Pellon® Peltex® 71 or 70:

For smaller projects use Pellon® Peltex® 70 just as you would Timtex®.

For larger projects that need extra strength to stand on their own, use a double layer of Peltex® 71 prepared in the following manner. Take 2 pieces of Peltex® 71 which are the size required for the project you've decided to make, and put the adhesive sides together. Cover it with a piece of muslin, then fuse them together. Follow the instructions in the pattern using the double layerd Peltex.® The cost of two pieces of Pellon® Peltex® 71 should not exceed the cost of a single layer of Timtex®.
