We enjoy colouring the Original DoodleArt Flowers poster as an activity to do in the evenings. This 24"x34" poster provides over 70 hours of creative colouring for the whole family. This poster kit includes 12 high quality, dual precision-tipped, washable, non-toxic colour markers. Since we did this activity as a family project we involved our 4 year old to participate in the colouring, although this kit is recommended for everyone over 8 years.
