Cut out the Apron you want and a little Bag.

Cover the part below with bias tape first.

Now it should look like that. :)

Cover the part below of the bag with bias tape

Then cover the upper part. Bag is now finished

Pin the bag where you want it and stitch it.

Now cover the upper part of the apron.

After you cover the rest with bias tape. Like the green line. You sometimes stitch only the bias tape.

Finish :)
