My mom used to make the Christmas balls and she also did eggs at Easter...this is the way that she did them...you get a styrofoam ball and you cute squares, rectangles, etc. in small pieces of fabric...you just lay it on the ball and gently push the fabric in to the foam...my mom would use a small screwdriver or a nail file to push the fabric in...you just have to be careful not too push in too far or the styrofoam will fall apart. Sometimes she would cover the seams with rick rack (attach with glue gun), other times she would leave seams as they are...she would use a straight pin to attach a piece of rick rack at the top to form a ribbon to hang on the tree....hope that helps.
