PLEASE do NOT use the glazed thread in your machine, it will gum it up and cause you all kinds of problems! It is designed for hand quilting only.
Nylon thread is rather an old-fashioned concept; I would recommend monofilament poly instead. Superior has a very good product called Monopoly (pronounced like two words - mono+poly, not like the board game). Unlike nylon, it is heat resistant.
The problem you will run in to with invisible thread is it's rather tricky to sew with. You have to set it up in your machine in such a way to prevent twisting as it comes off the spool or cone, and the tension needs to be loosened a lot.
If you're a beginner, definitely practice sewing with the monopoly before using it on your project. You may decide that it's easier to use a 60 weight brownish thread in the panel, then switch to orange for your borders, then pick a khaki to blend with the camo fabric.
Good luck!
