Hi Gal
It is personal preference...I personally never use homespun (solid/plains) and don't even own any! LOL
It depends what look you like - to me a solid background looks much more antiquey/old.
I like tone on tones - (eg small print!)
My advice - if you like it go with it, try your fabric against some solids and some not and go with what you like!
Hope this helps
Kylie
