First, cut the sewing patterns into squares and make sure the styrofoam is in the shape of a tree.
Next, take a retracted pen and wrap a piece of the sewing pattern around the dip.
Put some hot glue on the end of the sewing pattern paper and puncture the styrofoam with it. You want to make sure you are stuffing the sewing patterns into the styrofoam.
Repeat the steps over and over again until you have a fully stuffed Christmas tree craft. The tighter and closer you stuff the sewing patterns, the fuller the tree will be!
