Poly Burlap Deco Mesh, 10" x 10 Yards (White)

Can this be used for a classroom bulletin board?

where can I find yellow poly burlap? I want to try and make a sunflower wreath.

I want to make a folded pattern i can follow for pleated masks. Possible?

I am looking to make a breast cancer wreath.. is the pink the correct shade and will it work and look like burlap? I’ve never used mesh.
