Need some advice from people who have made their own kilts - about the actual process and the fabric used.

My boyfriend has a whole kilt wardrobe - several in traditional tartan and a khaki Sport Kilt. For casual wear and fun - and to be the ALL-TIME WINNER of the Friday Hawaiian "shirt" contest at work - he would love to have a kilt made of Hawaiian print fabric. Thus my quest for this Christmas. (I am aware of the new Hawaiian print kilts on the Sport Kilt site - but, no thanks. The fabric is too girly and looks like a skirt!)

I found kilt making instructions on this site (thanks!), and I've found several sources of Hawaiian print fabric online, but 99% of it is the lightweight cotton shirt fabric - which could be very, er, hazardous in a stiff breeze.

Can I add a lining (and what kind of fabric) to the Hawaiian print to give it some extra weight? What's the best way to go about doing that?

Any other kilt-making tips, word of wisdom, and best practices are greatly appreciated. Thanks!
