Ending1: You can use any type of bag that you like, but if you're wanting to make a cushion you can use a clay egg bag or rubber coffee pot.

[step] If you choose to use your own face, you will need to get it exactly right to match the shape of the bolster. Ending3: If you want a permanent bolster, you can use 3/4 yard of the fabric of your choosing and sew it shut. You can also use old towels instead of blankets, if you prefer. Ending4: If you are using a stuffing that you leave unsecured, like in a rolling suitcase or a tucked-in pillow case, use duck net to make the stuffing. [title] Decide where you want the bolster to be.
