I love the idea of giving something a bit more permanent for Valentine's Day, so I've been paying close attention to valentines either printed on fabric or in the form of artwork.  These vintage handkerchiefs from Bird and Banner are one of my perennial favorites, particularly for Valentine's Day:

These "much love" doily screen prints from Ashley G are incredibly sweet and perfect for Valentine's day:

And how unbelievably adorable are these fabric flower valentines from emersonmade?
