Debi, collages are fun. Think what you want to put them in. A frame, just a board or poster board?
Glue would make them permanent or you can buy photo corners to place them in the order you like. Decorate with paper or markers. Let your imagination go wild!
Hi Debi! I have listed some links for you to consider for your project. I wish you the best with it! Merry Christmas Debi!
You could glue a whole bunch of frames together of the same color or paint them or get a large poster frame and put pictures all diffrent ways starting in the middle and working your way to sides
here is a fun idea - https://youtu.be/xfVxvL0epes
