They grow up so fast! Don’t miss a moment! Build a growth chart that will give you a lifetime of memories. This Transfer includes registration marks that make it easy to properly line up the pieces of a 6’ ruler. Use Chalk Markers (item T193101 or T201102) or Chalkable Chips (item S191110 or S193101) to mark the height of your little ones (or big ones!). This makes great pieces to sell, and makes great gifts for new parents or grandparents.
