I was so tickled when I came up with the idea of creating a custom paint-by-numbers canvas for the Secret Garden Baby Shower. A party activity, a loving reminder of everyone who came to celebrate the arrival of the new baby, and a gift for the parents, all rolled into one.
I used the bedding the parents had registered for as the inspiration for my canvases.
I simply sketched my design on the canvas, decided which color should be which number, and labeled all the sections. Don't forget to use a marker to write the number on the lid of the corresponding color right away! I forgot to do that when I first mapped everything out, and it took a surprising amount of time to figure out what I'd intended to do when I went back a few days later to label the paints.
I painted a band across the bottom of each canvas, and when it was dry, I used a fine-tipped Sharpie marker to write "Painted with love by" on each painting. After painting a bit of the image, each guest could sign her name at the bottom with the same Sharpie, creating a truly unique, custom memento of the occasion.
I could see this working magnificently at a wedding as well as a baby shower. What if you took a photo of the venue ahead of time, and had a large canvas printed up for all your guests to paint and sign? Best guest book ever!
