So... I used this Steampunk Parasol pattern from Ira Rott to make a slightly larger one.
The pattern has a great chart and is easy to follow. I used almost an entire ball of Curio size 10 crochet thread in black, about 675 yards.
Here's what it looked like before sewing it to the frame... it's amazing what a good stretch will do.
I'm already plotting the next one. If you want to see more of my parasols, just use 'parasol' in the search box. They are addictive!
