Note: I will refer to my rectangle using cardinal directions and measurements refering to large and small scallops.
1. Start off with a piece of card stock larger than your intended rectangle size. Mine is a 3" x 3" square which gives me lots of room to work with to make a 4 large scallop x 3 large scallop rectangle.
3. Insert your Northern edge into Scallop Edge punch to create the long side of the rectangle. Align carefully and punch.
Your punched piece should look like the photo below.
Notice that the measurement from the center of the small scallop to the edge of your original card stock is exactly 1/2". This will help with trimming and alignment for your rectangle.
4. Trim your cardstock 1/2" from the last small scallop that you desire. In this case, I want my rectangle to measure 4 large scallops x 3 large scallops, so I am cutting my card stock 1/2" from my 3rd small scallop.
Your cut piece will look like this:
Your piece should look like this.
6. Again, cut your card stock 1/2" from the center of your last small scallop. In this case, you will use the last bump created by your previous punch.
7. Align and punch the third corner.
8. Now punch the long Southern edge, carefully aligning the Southeast corner on your punch.
You should only have a tiny bit left to punch!
