But how do you go about adding and adhering batting to a foam surface?
There are several methods….
In the SANDWICH METHOD a spray adhesive, such as Camie 303 is carefully applied to the foam. After it tacks up (30-60 seconds) the glued surface of the foam is placed on a slightly larger piece of Dacron. Use a scissors to trim. If the foam is for use in a two sided cushion, repeat the process on the other side, creating a “sandwich” with foam in the middle and Dacron on either side. The advantage of this method is that it is quick and easy, but it will require the purchase a good spray adhesive. Also it should be noted that this configuration, when placed inside a cushion cover will create a more square look since Dacron will not cover the sides.
In the GLUED METHOD Dacron is wrapped around a piece of foam leaving three sides open. These are then closed with a carefully placed line of Camie 303 spray adhesive. This method is illustrated in the very popular book, Singer Upholstery Basics.
A less messy but slightly more laborious twist to the above method is the WHIP- STITCH METHOD where the open ends are stitched together with a curved needle and heavy hand sewing thread or button twine.
Finally there is the STAPLED METHOD, where Dacron is wrapped around a piece of foam and then stapled together on the open ends. You can use an ordinary desk stapler, or to make it easier, you can use a scissors stapler such as the Stanley Bostitch type which use a crowned B-8 staple. Because the staple is nestled down into the plush Dacron, it is in no danger of catching finger or fabric.
Remember that in the glued, whip-stitched, and stapled methods, you want to join the Dacron together at the top edges of the foam. This way, any excess Dacron will be hidden by the cording. If you join the Dacron in the middle of the boxing sides, a visible bump may show through the fabric.
If you would like your cushion to have a plush “crowned look”, many upholsterers start with the sandwich method and then add a second layer using any of the other three wrap-around methods.
