A crimp is the outside cousin of the pleat. Where a pleat folds the paper back on itself inside the sheet, a crimp wraps around the outer edge, so the finished fold looks almost like a small Outside Reverse Fold sitting on both sides of the paper.

It is just as quick to make as its cousin. You start with a square sheet, white side up, fold it in half and unfold it, then make a pleat to the left, fold it back to the right, and finally fold the sheet in half again along your first crease. None of the folds have to be exact - roughly in place is fine - so it is a great one to practise without worrying about precision.

This is very much like a Pleat but made on the outside of the paper almost like an Outside Reverse Fold.

STEP 1. Start off with a square sheet of paper with the white side up. Fold the paper in half along the dotted line and then unfold it.

STEP 2. Next make a Pleat by folding the paper to the left along the dotted line. Your fold doesn’t have to match the one in the diagram exactly. It just needs to be roughly in the same place.

STEP 3. Fold the paper back to the right along the dotted line. Your fold doesn’t need to be exactly in the same place as the diagram. This is just practice. You now have a Pleat.

STEP 4. Fold the paper in half again along the crease you made in step 1.

The completed Crimp. Notice how it’s kind of like a pleat made on the outside of both sides of the paper.
