One more quick sewing test before I sew the side panels for the tilt-up camper - I wanted to test sewing in the plastic retainer strip that secures the bottom of the panels to the tub.
When I built my yellow trailer, I put Wrangler soft-top retainers on the top edge of the tub, they're done in black bedliner in the photo below. A plastic strip sewn into the bottom hem of the panel slips under the retainer, the same way the Wrangler soft top side windows work:
The plastic strip was cut from lawn edging I picked up at Lowes.
And one more sewing test below... the photo shows the inside of the piece I was testing above, you can see the plastic strip sewn in, but also on the other edge of the fabric I've sewn some 1" wide webbing inside the hem. The upper edge of the panels will be secured to the inside of the flip-up top with snaps; the webbing ensures the fabric edge has plenty of strength so the snaps will never pull out.
I have a couple of other sewing tests I want to do with the window screens, but since my first step will be sewing the side panels without windows, and then adding the windows as a second step, I'll do those tests when I'm getting ready to do the windows. For now I've done all the testing I need in order to sew the side panels.
