My parents are the age of most people's grandparents (late 80's) and at this point in their lives, material gifts mean very little to them.
They have downsized practically all possessions, but do appreciate anything related to their family and offspring.
For their Christmas gift, I am coordinating a visual family tree with the unique thumbprint, signature and birth date of each family member.
This Instructable has been written to provide an idea of the finished project, which is expected to be completed by Christmas 2013.
Step 1: Very few items are needed...
-free hand (or clip art) drawing of a bare tree
-a sheet of cardstock*
-several shades of green stamp pads
*while this Instructable uses cardstock to create the sample, many of my siblings live out of state. For the actual gift, foamboard is being used as it is more durable when traveling via the US Postal Service.
