Use an old tire to create a small backyard pond. My kids, 3 sons, have been helping with yard work and planting. They keep asking for a pond. I think this is a great DIY project to do outside with them. Looks simple.
Little Girl's room.I've always loved the girl owls! Cute idea for a little girl's room! If you don't wat to paint or adhere stickers to the wall for the name - use smaller wood letters painted a solid color and hang.
Fort idea for where the rocking chair is now in D's room. Use a tension rod between the furniture and the wall to create a fort. What kid doesn't love a fort? This would also make an awesome reading nook!
Great idea RE the twin mattresses. I also love the tree pictures on the wall! Love to display kid-made art in a kids room! Two twin mattresses, some plywood, and a great playroom that doubles as a guest room or sleepover room.
