If you have a child/grandchild that loves to express their creativity on paper, why not frame it? I personally like to use a frame with an insert like the Ikea one in this photo.
Use different frames and create a kids art montage that they’ll be proud of! Even write they’re name and age on it so that you can look back and see how their creativity developed over the years. It can also make an awesome, thoughtful gift for a family that works on a tight budget!
