They are just lovely!! Table toppers or a wall hanging just like they are. Pillows......I am sure you will get lots of ideas on the board here.
I haven't made one yet, although years ago I made something similar and used them to cover the big round Cookie Tins. Covered the can with fabric and the top with the folded piece. Made for really nice looking storage tins or for gifts filled with cookies or candy.
I think the dahlias may be a tad big for the tins though.
