Burlap fabric smells - unsafe for orchid use?

[farley101]

Ray, the project I'm looking at using this for is on some of the very tiny ghost orchids that were in the flask I bought. I have some hickory bark on the way for the largest of the group, but want to "mount" the little ones on something to get them to the point where they are mountable. Would the 3D Spacer fabric be suitable for this use?

Everything I've found is intended for seat covers or speakers, with terrible colors to match. Appreciate the input, would like to help these tiny ghosts get off to a good start.
