This template is most helpful. The sil-nylon I used is very slippery and difficult to fold and cut. This template made cutting much more accurate.
This is awesome!! I made the mistake of cancelling the pattern for the outline but i made it work. Highly suggest it if you don't want the extra work of measuring thrice then cutting once. I'm not very good at sewing, and my work is really shoddy but with the instructions given it kept me dry for few days without testing my tarp before use.
When sewing them I tried using tape but it wasn't holding so i put small stitches in points along the edge on the first fold. Extra work but it held the material better.
I have made tarps for a while. Many shapes and sizes. I always cringe when someone says, can I have those curves... If I charged anyone to make stuff I would definitely charge extra for this. I hated either figuring out the template or cutting. I don't have a large area to lay it out flat and because they are always different I would have to do it for each one. I had not been smart enough to keep my templates. Well when putting in a recent order an offer popped up for a winter tarp template. At first I thought I wouldn't because I don't charge for the work, but only for materials. Then I thought I might treat myself and got it. Just cut a 12' winter tarp with cat cuts in about 10 minutes. Well worth it.
I would highly recommend putting tape down directly on the template, then applying tape to that for the project. It helps for adjustment and removal.
