Piglet-sus! Build Part 2 Folding Fins

For sharp folds, pre-score the dashed fold lines. 

On your prints (and in the picture to the right) there are boxes opposite the leg and wing outlines. These are the colored backs of the leg and wing fins. When the fins are glued and folded over the cereal box middle cores, you'll cut through all the layers using the outside lines as a guide. You won't have to worry about lining up any lines on the opposite (box) side. The other side will be fully colored on both sides after cutting out the shapes. 

Here I'm using a strait edge and the backside of a razor blade to score the card stock folds. There is a few layers of masking tape over the sharp side of the blade (facing up) so I don't cut my fingers. 

You can also use the tip of a butter knife with no serrations to score the fold. 

Fold the pieces on their score lines. Set a piece of clean paper over the top and go over the fold with the back side of a burnisher, in this case, the rear of a Sharpie pen. 

 

Using clean paper over a burnished fold keeps the card stock print clean. If there is any dirt on the pen barrel or burnisher, it will transfer onto your fin!
