Based on my previous make of the Modified Jalie 2679 Softshell, here’s an unlined but fully seam sealed version for a lightweight rain jacket.
The pattern is the Jalie 2679 with my own hood pattern added to it. I also used a commercial seam tape to make all the seams waterproof. You can order seam tape online from Outdoor Wilderness Fabrics for a very reasonable price.
The seam tape requires a lot of dry heat from the iron, and a little care is needed to protect the surrounding fabric. I used the tip and edges of the iron only, and lay some cotton along the sides to help shield the main fabric. Seam sealing is TEDIOUS! It takes a good amount of heat to melt the glue properly and I found myself making multiple passes. On the other hand, seam sealing is EASY, and with the right fabric, anyone could do it.
Otherwise, the build-up was the same as the original Jalie 2679 in Heavy Fleece.
Here are some final pictures:

I had no idea this was a thing. I thought taped seams were just like Hong Kong seams lol. I have a Prym mini iron, would that make it easier do you think? Or were you using a mini iron too?

I think the mini iron would be great, so long as it gets hot enough. It takes a surprising amount heat. I have considered getting one for this, let me know how works!
