I'm suppriset on so many good ideas for solving my problems. So, I will not use velcro and fasten the kilt mybe with buckles. Yes lining the under apron will help and will be done. X-Kilt instructions are quiet good. The only thing not completly understandable for me is revers pleat, specially the part on stiching it from waist to fell. Should it be stiched or not??

Thanks to all

Regards!
