NJ Quilter

Hi folks. We are in need of a new bedspread. Yes, I know - make a quilt, lol! But what I truly want is a Mariner's compass quilt and I've yet to see a pattern that comes close to what I have in my head. So, short term I'm planning to make a quilted reversible, 2 color bedspread.

I'm planning on using 108" wide fabric from Marshalls Dry Goods. Ideally I would like to use the same fabrics to bind but reverse the binding but to do that I think I would need 3.75 yards of each fabric. My quilters bible says I need 1 1/8 yds of fabric for a double fold binding of 2.5" for 400-440" worth of binding. 108 x 4 = 432 inches of binding fabric. I usually cut my binding strips at 2.25 vs 2.5. But if I'm going to do the 2 color binding I think I'd cut each at 1.50" so when sewn together I'd have 2.25"??? Am I thinking that through correctly?? Both cutting width as well as yardage requirement (.75 yds extra of the fabrics just for binding).

Also, has anyone purchased from thecottoncupboard.com?? I want to use Quilter's Dream Deluxe batting for this project and their price is about $10 less than anyone else for a king size batt. I usually use W&N but just finished up the roll I've had for years and wanted to give the QD a whirl and thought this would be a nice way to figure out how much I like it compared to the W&N.

Any comments/opinions on either or both of these questions are greatly appreciated.

Thanks,
Kim
