I purchased a daybed for our new home to be used as a bed if we ever happen to need one. Most of the time, it will be used as a sofa. I want to place two wedge bolsters across the back and a single rounded bolster on each side. My questions are:

1) What size wedge bolsters do I need? I need a pattern. Do you know where I can locate one online for ordering? I live in a rural area. Today, I drove over an hour and a half and could find no pillow forms or patterns. Online is my best resource.

2) What size round bolsters do I need? I need a pattern. Do you know where I can locate one online for ordering as well?

Thanks for any help that you can provide.
