Ribbon Christmas Tree Ornament

I've heard these called a "Ribbon Pinecone Ornament". They're very pretty, but take a bit of patience to create.

3 yards 7/8-inch-wide ribbon (I used felt ribbon, but you could use satin or some other type -- you need a kind that lies flat. Do not use wired ribbon)
3-inch egg-shaped Styrofoam ball
110 1/2-inch sequin pins
20-inch length of 1/4-inch-wide
2-inch pearl-head hat pin

Cut 7/8-inch ribbon into 55 1-3/4-inch lengths. Fold top right corner and top left corner of each length down to meet in center of bottom edge of ribbon to create a triangle.
Starting at narrow (bottom) end of egg, position triangle with the edges facing inward (so you just see a solid triangle). Pin in place, using one pin at each top corner. Continue with other triangles, overlapping slightly, to completely cover egg.
Loosely loop 1/4-inch ribbon back and forth to create a hanger. Use hat pin or hot glue gun to attach to top of ornament. You can see that on my ornament, we hot glued a mouse and a few small decorative pinecones onto the top for added decoration. This is not necessary, but it is cute.
