I looked at doors but all the non-custom offerings were really expensive and marginally useful and... ugly.
So I put up a tension rod and bought el cheapo curtains from Amazon until I could figure out a better way.
But I've never loved them. Plus Biggie and The Smalls clawed the bottom so they are full of snags at the bottom.
So today I went to my wall o' fabric stash and found the answer.
This fabric is some I found at Goodwill a while back. It's a polyester that has a great drape but really isn't that well suited to be made into the clothes I wear. But I loved it and it was like $5. And it's been sitting in my stash waiting for its turn.
Now is it's turn. I need to hem it up - bottom, top and sides and then that corner will be a star!
