Still waiting for our maiden voyage but had wondered abou thow to cover those vents in our Silver Spirit. This idea beats duct tape! Another thought might be to stick it on with velcro dots around the vent, but I'll bet the snaps would work better. Very cool idea.
Back to curtains

I had what I thought was a brilliant idea while in K-Mart and bought two placemats that look like woven wood and was hoping they'd be big enough to make roll-up shades with (I was going to back them with fabric (would have to glue, tape, or velcro) and sew on ribbons at the top, front and back, to tie the rolled up shade with. But they're too small. Considered extending themusing fabric and still might. Fortunately they only cost $3 total and I can still use them on our kitchen island as placemats.
So then I found a beach mat (one is plenty big for two teardrop shades) for $1.50 at Big Lots (you can tell I shop all the trendy places) and my latest scheme is to cut out the shades from that and bind the ends with ribbon (my comforter was a set that included a dust ruffle with a ribbon all the way around so I can cannibalize) so I might use that. Good idea about testing it with the lights on. I think before I start sewing I had better check and see if I should put fabric backing on it, too. I think it might be cuter with just the ribbon, but who knows? Good chance to use up some spare fabric that's been sitting around--not thrilling but harmonizes with the comforter--of course then I don't get new fabric!. I'm enjoying this dilemma!

The planning is so much fun!
