How can I use pictures on old calendars?

You can frame them either by placing them in a mirror with a mat or you can get the kind of frames that have a clip so you can change it out. Old clipboards also make cute vintage looking frames.

Barbara, Glue them on. Aloha!

Make your own greeting cards. Make or purchase frames and change seasonally for instant cheap decor. Use for mod podge projects.

some of mine are framed.

You could decoupage them to the cover of spiral bound basic journals to dress them up.

Donate them to a local primary school, or kindergarten centre, especially one in a less advantaged area. Children love to 'cut and paste', and more often than not, there is just no money for these kind of materials.

Laminate them and make wipable placemats.
