I made this card with my toddlers and preschooler: http://www.brilliantbeginningspresch...eces-card.html
Next week we are going to make a mini version of this in a mason jar with succulents instead of cacti: http://www.abeautifulmess.com/2013/0...i-garden-.html
My toddler boys aren't really into painting or colouring yet so I thought they would have more fun with the assembly process of dirt and rocks :-)
Then put it all in a paper bag decorated with stamps and stickers!
