Hi Luis,

Icarex works fine, just follow the instructions in the sailmaking notes regarding how to line up the material towards the lee side.

I have a bunch of old spinakers lying around (in bags), the crispy stuff is the lightest (and the noisiest) and that's what I use for my sailmaking experiments (hence the wrinkles in my sails).

When you get some, also get some 6-8 mm double-sided tape to stick the panels together.

Regards, Jan.
