Thin fabric
 

I have a couple of pieces of fabric that have nice prints, but are much thinner than regular quilting fabric. Is there a way to use interfacing to get them up to weight, or should I just get rid of them so I'm not tempted to try to use them?

I used thin iron on interfacing on a solid that was the color I needed, but way too flimsy.

I try to use all the same weight fabrics on a top. But that might just be a personal preference.

By "thin" - do you mean loosely woven?

I have used a thin fusible on the back of white fabrics (for piecing) to make sure there is no see through, so yes, you can do that. As long as the thin fabric is 100% cotton, you can use it.

Can you make a test block and turn that into a mini quilt, complete with binding and batting and throw it in the wash to see how it holds up. I know it may not be worth the effort but it might help with your decision.

Are the fabrics a name brand? I find some Moda fabrics to be thinner feeling than some others, but they are strong so it's not an issue.

Double it and use as a backing. That is my plan for 3 thinner fabrics I bought years ago. I just haven't decided it was time to use it.

I doubled it when making a child size quilt for charity. It turned out fine

They are nothing special. I experimented making magic hst's with them, and even starched to death, they were an unmanageable mess. Stretched and got wavy along the bias seams. So, interfacing for sure if I ever use them. They are not particularly loosely woven, just really flimsy. Thanks for the advice, all!

A lightweight fusible interfacing will take care of the problem. I’ve needed to use interfacing many times in quilting projects. They turn out fine and the fabrics hold up well. I ( generally) use a Pelion, lightweight non-woven fusible interfacing. I purchase it by the bolt.
