I have also been looking to find information on building sport kites to try and make some of the OSTK ones out there. But…the link that many have highly recommended in the past(https://www.tweelijners.com/tom/tomskitesite-en/KB0.html) does not appear to work anymore. Does anyone know of similar resources to learn how to build (sew, cut, materials, etc) for making OSTK kites like these, https://www.kareloh.com/kite-plans/
Thanks for any help!
