I started a footprint canvas for each of my girls when they were born, taking one footprint every month from newborn until their first birthdays, and also taking handprints at 6 and 12 months. I love to see the progression as their little feet grew and became more defined, and now that we have two little treasures its interesting to see the differences and similarities. Footprint canvases can be made at any age and are such a sweet reminder of how tiny (or big!) those little feet and hands are. I used baby safe ink for my canvases, which I bought in ink pad form from Ebay.
