i am officially requesting a 10% kickback for using my design.
or, you can send me a REAL Guiness. the sheit we have over here in the states is only 3.5%
i agree with the others, that quilt looks real nice. i used a sewn thru model similar to your design and it worked great to 42 degrees.
mine was in the 10oz neighborhood. but not nearly as water resistant as your fabrics, im sure.
have fun w/ it!
