One of the most important things to do is to display your child's/children's artwork in your house. It can be in the kitchen on the refrigerator, on the pantry door, in their play area, and of course in their room. It is great way to show them how proud you are of them in their accomplishment.
In our home, after each day at school. We display our daughters work of art on the refrigerator. If it is a large sheet of paper then we display it on our pantry door. Over the course of the days (in between classes) we talk about what she was drawing...how she pasted the tower, etc. She gets so excited talking about it. Each month, we rotate the artwork she has done in her room.
In her room, we have created a little gallery of artwork. We went to Target, in the photograph frame area, we purchased acrylic frames where you can easily remove the back of the frame to insert anything that you wish. We let our daughter select her most favorite pieces that she did for the month, we place it inside of the frame and then rehang it back on the wall.
It makes one of the neatest looking pieces of art in her room and it makes it her room even more, because it is something that she has done and is very proud of it.
I was looking through a magazine and saw another way you could display your child's artwork. I thought it was really a pretty cool idea. Go to a Goodwill, Salvation Army store, etc and purchase wood photograph frames. The wood frames can be all different sizes. Paint the wood frames any color that you would like. Remove the glass, the mat, etc. because you would not be using these pieces of the frame.
Once the frame painted...arrange the frames on the wall, any way that you like. Each time your child brings home a piece of artwork, get some sticky tact (something that will not hurt your wall and place it behind the artwork and display on the wall in the middle of the wooden frame. Whala you have a piece of artwork in a frame. The great thing about using this type of frame is that you can easily remove the artwork to insert something new in it.
