Foam is available in 2-6mm thickness. The designs shown in the catalog were sewn using the 3mm foam. The thickness you choose depends on the effect you want to create.
A spray adhesive may be used to hold the foam in place, although it is not necessary.
Sewing tensions should be loosened to keep the foam from pressing down.
Each design will have a color change run an "outline" for the puff area. This shows you the area(s) that will be using the puff material. After the outline is sewn, lay the puff material down and start the next color.
The color change sequence for each design will indicate when to "apply" and "tear" the puff material away from the design. Do this slowly so the material won't loosen in the hoop.
The color of foam used should be closely matched to the outside column of the design. For example: If the column around the outside of the design is black, use black foam under the design, regardless of the other colors that may be used throughout the design. This helps eliminate the foam showing through the column.
If foam pokies are sticking out around the edge of the stitching, use a blow dryer to shrink.
