Here's how it works
Cut stripes of the different fabrics about 6 cm wide.
Pin a strip of patterned fabric wide on a tip of the egg, fold the edges inwards and wrap the strip irregularly around the egg, fixing it with decoration-Pins
Then work in the same way from the other side, then wrap the remaining free area in the middle with plain fabric. This will cover the edges of both pattern fabrics.
Now fix the transitions between the different fabrics with Deco-Pins so that no Polystyrene is visible anymore.
Finally, spread satin scattered roses with simple Pins on the egg.
