You can use wood and natural elements in about any part of your wedding stationery from invitations right through to seating plans and place cards.
Pallets are easy to find and great to work with. Their size allows for excellent seating plans, welcome signs and smaller information signs.
Transferring or painting your exact design onto wood can be a very simple and therapeutic, however time consuming task.
Corks are very easily available and many wine farms are quite happy to let you take them off their hands. I find these used ones work better than brand new corks.
Adding text to wooden invitations can be done in a few ways. You can have this lasercut into the wood, transfer using a number of methods or have a stamp made and using an ink pad, stamp information directly onto the wood.
