After making two flannel jammies for my niece and nephew, Thor and Katie, I took the easy route with my son Jack’s and my niece Haley’s pjs. I made them another set of Kwik Sew 3510 knit jammies, like I did for all the kids last year. Here’s my pattern review from back then. Again, I did not have any issues with sizing. And again, I constructed this almost entirely on the serger.
I did have two things different this time around though. I have a new tool that I wanted to use in this iteration, a stretch twin needle for the hem. The knits I used, a plane camo from the FabricFairy.com and a red and white stripe knit that I can’t remember where I bought it, were pretty stable so I didn’t have to stabilize the hems at all. I fiddled around with stitch length and thread tension and found that a length of 3.0 and tension of 2 was perfect for the twin needle stitch. It made a beautiful hem.
When I made the sleep sack (review forthcoming) for my niece Chloe, the instructions said to top stitch the neck band SA to the body of the sack. I loved how finished the inside looked without that SA flopping around so I used that trick for Jack’s and Haley’s knit jammies too. It looks great!
That’s about it. These are pretty quick and easy jammies to make. Not a lot to say. So let’s just look at Jack shall we (sorry no picture of Haley yet as she hasn’t received the pj’s yet)? 
Thanks that was really helpful serger info. They look beautifully finished. I am getting ready to delve into knits – with apprehension…
Nice and boyish looking. I love the retroish airplane print you choose. PJ’s create nice memories.
Very cute sets pf Pj’s and your hems look perfect.
Great jammies for a little guy.
