It wasn't that hard .... you could have done it, right? :lol:
I didn't allow for the seams when joining the strips ... and if you're joining them on the bias, that'll chop them down a bit further. I think the bias joins look much nicer than the blunt straight ones.
Because of this, I'd add on an extra two or three strips to the 1000" to make sure you have enough.
Better to be too large and cut it to size ........ than too small and be disappointed.
Good Luck :lol:.... when you get it made, would you please PM me, so that I am sure to see the finished results, being that I've helped design it!!! :)
