Here is an ubber cute shower invitation idea from good old Martha Stewart! Take mini cutting boards and attach the invitations to them with ribbon. This is great to set the theme for a bride that needs her kitchen stocked or just loves to cook! Plus, it gives your guests an invitation they will defiantly keep. You can have invitations made, or make them yourself. Center each on a board; attach with double-sided tape. Wrap with ribbon, and mail in a small padded envelope. Mailing the wooden cutting boards could become quite pricey, so check that out first if you are on a budget. You can also find plastic cutting boards which are cheaper and do not weigh as much. These are typically white, so you may want to get a bolder color for the invitation if you go this route.
