Yes, crochet designs are meant to be sewn on something. It's easy to get it mixed up with fsl. It is a lovely set.
If it is the crochet style set it states they are not FSL. You could stitch them on organza and then cut them out around the edges. Happy stitching!
I know how disappointing this is. I did it once and now I make sure it is FSL before I start. There is always so much to learn.

These look like the set Crochet style teapots, and it states they are NOT FSL... so they need to be sewn on fabric. It's too bad you didn't see that before you got them and sewed them out :(
How frustrating. They look like they would have been lovely. I would contact the designer.
