Part 1: Cat curves and fabric cuts
I will show you how I made the patterns for the catenary curves and cut the fabric for the winter tarp. In this video I use XTrekker's Catenary Curve Calculator.
Part 2: Sewing the ridgeline
I sew the ridgeline using the flat felled / french seam hybrid method.
Part 3: Tie-outs
I'm deviating from the sequence of the pattern a little and I'm attaching my tie-outs so that the webbing is on the inside of the reinforcement fabric. It works out and I am happy with the product.
Part 4: Rolled hem using the *rolled hem foot*
I hem the tarp, including the catenary curves, using my 1/8" rolled hem foot.
Part 5: Side pull outs
I attach side pull outs to the tarp, and like the tie-outs, I'm deviating from the instructions somewhat.
I use Silnet to seal the seams on the ridgeline and the side pull-outs.
