Got an email back from Kathy Lare at Kathy's Kilts www.kathyskilts.com and a member of this board.

I'm a big guy, 52 jacket. She says a yard of the new X Marks Tartan material would be enough for a full front and back vest for me. If I do a tartan in the front only vest just a half a yard.

Thought this might help with our X Marks Tartan project for folks who wanna add on to their kilt (no not wear them together), or who would only want a vest to wear with a solid color kilt.

Think she charges about $125 to sew up a vest.
