I tried to create my own curtains from inexpensive muslin and they did not last long.  Having the correct fabric is key.  These are a little more sheer to my preference but I cannot complain, the price cannot be beat.  I would recommend these. By the time I shopped for a deal on bulk fabric, made a trip to the store to buy it, spent hours cutting and hemming to these dimensions, I had a lot of time invested.  I spent minutes ordering these for less money in the end and they shipped immediately.  Lesson learned!   Pros: great value, great upgrade for the deck/pergola, filtered sunlight Cons: on the sheer side so do not expect full privacy
