How thick should my window seat cushion be AND yardage?

Posted by sarajon (My Page) on

I have to get a cushion cut for a window seat, what thickness would look the best? The old one that is there now is over 4" and kind of looks like an outdoor cushion. I was thiking 3"?

Also, what yardage for 98" long, 18" deep 3" thick and the fabric is 58" wide with a half inch repeat. I do want it self welted and like the 8/32" welting size.

Second cushion same dimensions but only 45" long (still 18" deep and 3" thick) . Using same fabric but different color, how much for this?

I've looked online to find some kind of estimator to no avail, any help appreciated!

You need 3 yards of fabric for the larger cushion plus a yard to make about 13 yards of piping. You need 1 2/3 for the smaller, plus about 2/3 yard to make 7 yards of piping. You can find charts for piping if you do a search for "continuous bias", that is what they cut to make piping. Most of the charts are for quilters so they are calculating based on 45" wide fabric. That means the quantity I've given you for piping is generous because your fabric is 58".

Use the 4" green (high density) foam if this is something that you will sitting on frequently. The 4" is for comfort. If that is not an issue, use the 3" green foam.

You can find the green foam at Joann's or try the link below. They have a green foam called Lux foam regular that sounds like what I used.
