To pin or not to pin!

[Tartan Tess]

There are pins that look just like this in yellow that you can iron over. Don't know the brand.

On my latest (DIY #5, 8-yard Jura) I first pinned at the waist and bottom of the fell, then basted the portion of the pleat to be sewn down and removed the pins before stitching. It worked very well.

First, whatever works for you is what's really important. Having said that, I'm not a big fan of basting a pleat before stitching because, once it's basted, there's no adjusting without taking out all the basting. Pinning the pleat well from the bottom of the fell to the top is quicker, holds at least as well (and in my estimation actually better) than basting, and can be adjusted easily!
