We are doing something similar to the idea.
My fiance's BM is a great artist. I have asked him to paint a tree- actually its the 100 year old tree with a tire swing, which resides beautifully in our back yard.
At the wedding I will have a table set up with ink pads ( in orange, yellow, red) where people will dip their thumbs into and make "leaves" on the tree and sign their name. The painted tree will be bare friends and family will fill in our tree
The BM will also pain our dog and four ducks at the base of the tree along with our initials in a heart in the middle of the tree
When we get home I plan to frame it and hang it over our fireplace
Don't worry there will instructions and and hand wash
