Christmas gifts come out of the glowforge before Christmas. But after Christmas, that is when gifts go in the glowforge
So I decided to put my pink Columbia soft shell jacket in the glowforge because the soft shell is actually 100% polyester. It folded up perfectly in the glowforge. Settings I used was full speed, 10 power, 225 LPI, and 1 pass.

I engraved this soft shell jacket from costco:
