The Dollar Tree stores have awesome
silver bells! They are meant to be ornaments and come in a package of 9 bells. They have a snowflake cut out on the bottom and star cut outs on the top and they are about 1 inch round. I bought three packages of those and two packages of elastic cord at Michaels and I am SOOOO happy with the bells my kiddos will get.
Last year, I bought the smaller bells in packages from Michaels, but they weren't very jingly.
