I was finishing up my Christmas shopping yesterday and stopped by Old Time Pottery on Morse Road (near the intersection of Morse and Cleveland) and noticed they had a lot of stuff for low prices that might help out a DIY bride.
They had glasses for $1.00, open stock plates and cups, lanterns, vases, etc.
Another place to try out for decor is the store At Home (former Garden Ridge) in Hilliard. Not as much for dinner supplies, but a lot of cheap decor.
