Thanks for the help. I'll look into the options. I'm about 70 miles from the nearest Joanne Fabrics so I may stop in there some day to ask. As for the Rochford Supply link westend gave me I may do that except I'm not sure how many blocks I need to buy. My couch is 2 chunks the bottom measures is 76X26 and the back measures 76X16. If I only do the bottoms of the dinette seats I would need 2 chunks both of which measure 36X24. So how many 24X72 inch blocks would I need to order to have enough to do all of that??? It's all 5 inches thick.
