Window Seat Cushion Length?
Hello, I just sold my home and bought a new condo. I have a lovely window seat in the master bedroom. I went to an upholstery shop yesterday and the cost to have a cushion made was out of site. So, I will be sewing one even though it is not my favorite thing to sew box cushions.
I will order cut foam either 4 or 5 inches thick and also nice and firm from somewhere on the web.
The question I have is this. The window seat is 15" deep and 100 inches long. The upholstery shop said they normally do just one cushion for a window seat. Do you agree with just one cushion or would you make two or three instead due to the 100 inch length. Then again, would 2 or three have a tendency to slip/slide crooked more than one continuous cushion.
Also how long does the zipper need to be in order to make it do-able to get the foam inside. From the back center how close to the end of the cushion should the zipper be?
Thank you for your advice
