Hi Claire, this is Rose to answer your question here, why when you have the right click on to the dart it doesn't give you the. Option on creating the dart, so I'm going to zoom in a little bit and I'm going to show you why. So for example, right here I have two. Points right there, one point is on top of the internal line and the other point is on top of the pattern outline. So if I hover my mouse onto that point right there, first of all, be sure you are on this edit pattern. Tool right here, OK? If you're not yet on it, click on it to select that tool right there. Right there. OK edit pattern tool. Click on it. Then hover the mouse onto the point and I'm going to right-click so as you can see right here. It gives me many other options except. To add dart OK, so it's giving me a delete point. Lock, add notch. But no add dart, so I'm going to press escape on the keyboard to get out of that. Now I'm going to hover my mouse onto this instead. See, right t
