Very cool large wooden buttons. Light or dark finish. Approximately 2.5 inches across. We use these so many ways! The centers for hooked or punched flowers, bases on woven baskets, buttons on big slouchy wool bags. 
The larger big buttons are 2.5 inches and what we used in our medium and large pumpkins. The medium plain button is not quite 1.5 inches and perfect for the small pumpkin projects.
