While I mostly used white card stock for the basic folded greeting cards yet I just found out how great it is to use my own printed papers, because they are white inside and beautifully patterned outside.
I use light card stock to print the letter size sheets. Then I fold them and run them doubled through my Big Shot die cutting machine. I once invested in a set of simple rectangle dies with a small embossed edge and I use them all the time.
You can align the folded card stock just before the die cut line. This is how you don’t cut the edge.
Then I used some clean plastic cheese packages to make “glass” layers for the fish bowls with different Tim Holtz dies.
The fishes are from my fishes collage sheets cut with the Silhouette Cameo. The bird is one of Stamper Anonymous Bird Crazy stamp.
