You are your own worst critic. What you think is terrible......others might find great. Don't be surprised or upset if the pieces don't quite meet...... or the angles off.....or what happens sometimes, it doesn't fit. That just means you got in some good practice for you next piece. Before folding, make sure to score the lines. There area several ways to do this. For some, they use different colored pens to indicate mountain or valley. Others use the back of their X-acto blades. However you do it.....make sure to do it straight. A ruler can help. Not a plastic or wood one. A metal one. This way you not only get the most accurate line when cutting, you don't have to worry about cutting you ruler to shreds w/ the blade. This is useful when using a blade rather than scissors to cut out you're templates.
