Dart Manipulation Pattern Making Tutorial

PatternLab gives you a large variety of dart manipulations to choose from when it comes to designing your basic blocks & slopers, but sometimes that’s not enough. Perhaps you want your French dart to be slightly lower than the standard that we provide, or maybe you want a curved dart? There are so many options available. This tutorial will teach you the necessary tools you need to add your own custom dart placements and dart manipulations to your PatternLab basic block or sloper. It’s a simple yet powerful technique that is well worth learning.

Basic Block/ Sloper Elements

You can apply this tutorial’s techinque to any basic block that features darts, however, for this tutorial we recomend starting with something simpe such as a basic bodice block with “Classic” front darts.

To save time, click the button below. We’ll create a basic block (in the Lab) that already has this dart preselected for you. All you’ll need to do is select a profile or one of our standard sizes. Don’t forget to purchase your block as an ePattern and not a PDF! PDF patterns can’t be edited, they can only be printed on paper. ePatterns ar fully editable digital basic blocks.
