Funny you should ask now. I just - as in last night! - finished making roll up window shades from Ikea woven panels. They have several types of fabrics and one woven kind. What I can tell you about the woven type is this - if you were to vacuum them a lot, the edges would concern me. I think they will show the abuse from that. However, I banded the edges of mine with fabric and that protects that vulnerable area. Not certain how the fabrics would hold up. The only one I really looked at was a semi-shear with a white on white pattern and obviously that would show your red dirt a lot.

I can tell you this much about the Ikea ones - the base price of the panels is very reasonable but it's all the hardware and tracking required that runs the price up.

dlm2000 -- Thanks. I looked at the Ikea info. Their hanging rail doesn't come wide enough for my windows. I appreciate your point about the unraveling edges, though, and will take that into consideration with any other brands I find. (Not the biggest selection of anything on Maui, but getting better.)
