Years ago at a friend's house I discovered that she had purchased a fabric tablecloth to use as a curtain when used with the clipping drapery rings that slide over the curtain rod.
This turned out to be so much more cost effective--especially since we needed 104" long curtains. I got each of these tablecloths
(60" x 104") for around $11 at Target. The rod was one we have had for years and the clipping drapery rings were $12 for 2 sets.
