Received my scrap pieces of silnylon and started to practice sewing. Bit more difficult than my experience practicing with basic cotton/poly fabric.

The issues:
1. Unlike fabric it's a difficult to hand press a fold before hemming. Any hints & tips to maintaining a consistent even hem thickness?
2. Starting and finishing a stitch line. The lower or upper layer sometimes times slips.

Would like to avoid pins. Any other options? Is pressing with a very low temp setting on an iron even possible with ripstop or silnylon?
