This pattern is rather schematic. I tried to write all the necessary informations, and I think, it is clear enough for those, who like filet crocheting. If you are insecure in filet crochet, there are many tutorials on the internet, and in written. I too learnt it so :)

For the frames you can dismantle an ordinary umbrella, that you can buy everywhere.

Have fun with the pattern. If you had any question, contact me freely, I try to help you :)
