I really don't like the curtains that are in the Casita currently ... they're actually just neutral draperies that the previous owner cut down and they do match/coordinate with the cushions so I'll save them in case I ever decide to sell her (doubt it) but since she's going to be done in a cottage theme, I've decided to attempt something.
I'm going to use vintage pillowcases that I have tons of and see if that works. I've got sets of them with detailed embellishments ... embroidery, crocheted/tatted edges and I've picked out the ones that have the most pink in them to kind of have them coordinate. I'll use 2 on each of the 3 windows in the back by folding the bottom edge over and making a pocket. The previous owner had a brilliant idea of screwing a little curtain rod into the frame of the mini-blinds so will use those.
I've sorted pillowcases, measured and ironed them and now all I have to do is sew a straight seam on one as a tester and put it up. Hopefully this works and doesn't look goofy. I've seen it done in another camper and it looked really cute so we'll see.
I'll post pictures as soon as I get the curtains up this weekend. I'm also considering using a white eyelet comforter on the bed so will be scouting around looking for one although if I find a pastel polka dot or a nice non-gaudy plaid, I might be really tempted. Hurry spring!
