Pamela,
Yes! Crispy's correct. If you see a fabric and you read it is "floral", by all means, use it!
I personally do not have plans for any florals yet, but that doesn't mean I shouldn't! My husband is SO not understanding my enchantment with this group and our fabrics. He just nods and smiles. Of course, that's what I do when he starts talking mechanical stuff, too.
