If my math is right (and I make NO promises!) here is what I think might at least get you in the ball park. Each of your 2.5 x 18 strips should yield 6 2.5” squares, which finish at 2”. So, for a 114” x 116” top, you need 57 x 58 squares. That’s a total of 3306 squares. Divide that by the 6 squares per strip, and you need 551 strips of fabric. It seems pretty intimidating, but a many trips isn’t any different than joining other kinds of blocks because each “trip” is it’s own block. You may have to adjust how many trip blocks you want to use so you end up with square trips. For example, if you make the trips 8 squares x 8 squares, it would take 7 trip blocks per row and 7 rows of blocks. That would make it 112 x 112. Then adjust to the full top size with a border. Someone please correct me if I’ve not thought this thru correctly. Then we’ll both have learned something (0:
