I've volunteered to make cushions for three small pews; I did a job like this once before -- in 1960. After nearly fifty years, I'm a bit fuzzy on how I accomplished that, so I thought I'd better run my plans past you guys first.
The seats are all 15" wide. (38cm)
One is 68" long, the other two 41". (173cm, 104 cm.)
I figured I'd tell Pastor Bonny to buy a piece of one-inch foam that's
69" by 15.5", and two pieces that are 42" by 15.5. This way one inch of length and half an inch of width will be squished up to keep the cover taut.And I'll tell her to buy fabric anywhere from dress-weight denim to upholstery-weight in thickness. (She has a better eye for what looks nice, so I'm leaving color and pattern to her.)
I plan to make a pillowcase that, when flattened, measures one inch longer and wider than the pew seat, to allow one inch all around for the thickness of the foam. I also plan to make the opening in the middle of a long side, to give myself a prayer of getting the foam in after sewing both ends of the seam so I don't have to slip-stitch any corners.
Before turning, I'll sew off a triangle at each corner to make a box shape. Seems to me that if I make the corners one full inch high, there'll be a little poochy place at each corner, so I thought I'd sew only half an inch off, and the oversized foam would stretch it into a sort of rounded profile. Maybe 3/4" would be better?
Have I missed anything, or guessed wrong someplace?
