I've been using trades to decorate around the house. There are more trades that did not fit in the pictures.
For the hanging ATCs I used Tim Holtz clips. The large ones have holes at the top that I could used to thread yarn. Since the banister can be seen from both sides I have two ATCs for every clip so there is art on both sides. For very light cards on our hearth I was able to use the smaller clips which are surprisingly strong. I also got table card holders that are used for place cards and these are great for displaying the art upright. (Also great for displaying photos - especially at Christmas.) In a few weeks these displays will change over to Christmas.
