Jon Jon Sew-Along: Day 3

This is the Johnny Pattern made up as a shortall for Easter!

It’s Day 3 of our Jon Jon (a.k.a romper or longall) sew-along and today we are going to finish our project. For those of you just joining us, we are sewing the Johnny Pattern from The Children’s Corner.  If you missed Day 1 or Day 2 of our sew-along, no problem! This sew-along will stay on the site and you can catch up anytime you like. If you have any questions, just post them in the comments section of the blog and I’ll get back to you.

TODAY’S GOAL: Finish our Jon Jon!

We left off with the our lining and main fabric sewn together along the top edge, around the neck and arms. With strap corners clipped, we are ready to get started.

STEP 1: Turn your Jon Jon right side out. You can use the flat or dull end of a skewer to carefully and slowly poke out the corners of the straps. Now Iron.

STEP 2: This is optional. Try topstitching that seam.

A quilter’s walking foot really helps you smoothly top stitch, especially through the bulkier seams.

Just stitch 1/8 of an inch from the edge all the way around that top seam for a nice finished look.

STEP 3 – It’s time to sew the seams at the bottoms of our pant legs. Pull out the instructions that came with the pattern. You want to look at step 8 in the printed instructions. NOW, a little pep talk (the one I wish someone had given me). There is a part of sewing that feels like origami and this is that part. Just trust the pattern and trust the instructions. It will work.

Pick a pants leg and grab the bottom side seam of the romper.

Working with the same leg, grab the side seam of the lining with your other hand.

Now, with indifference to the rest of the outfit, flip those side seams around so that you have smacked them together, right sides facing each other and side seams matching.

In this pic, seams are together, right sides facing each other! Look at how it’s twisted the rest of the outfit into a hot mess. It will work out in the end, PROMISE!

PIN and sew. Now, flip right side out and press. Repeat for the other leg.

STEP 4 – Press the pant leg seams.

STEP 5 – Now, the only raw edges left are those for the crotch. Simply fold the raw edges under, pin (matching center seams), and sew.

STEP 6 – Now you are ready to apply your snaps. I use the snap setter and size 16 long prong snaps. They offer full instructions on their website and on the package. For longalls, I apply 10 sets of snaps. For shortalls, I apply 4 sets.

STEP 7 – Time to work your button holes and add buttons. You can have two buttons on each strap or one larger button which ever you prefer.

TIP: You will NEVER regret working a test button-hole using scraps of your main fabric and lining fabric. It’s a great way to catch mistakes or to make adjustments before working them on your finished garment.

YOU ARE DONE! You did it : )

Now it’s time for the catwalk…

Have a great weekend, time to make another

    I was having trouble sewing the legs and getting the Jon Jon turned correctly so I went to your site and got it right in no time! Thank you. The pictures really helped!

    I was in the middle of making my first Jon Jon, following another tutorial I’d found. It did not explain the sewing of the legs well at all!! I was so frustrated and then found your tutorial! Thank goodness! So helpful! Thank you so much!!

    I am becoming obsessed with this pattern for my grandson! Do you use any interfacing between the face and lining on the strap where the buttonhole will be? I have found mine to be a little flimsy, especially when using microchecks. I do use a tear away stabilizer on the underside of the buttonhole.

      Yes, Sharon, you certainly can. Whenever I add interfacing. I use iron on and am carefully to cut the interfacing so that it will NOT extending into the seams. Interfacing in the seams can be bulky and difficult to turn those straps out or top stitch (should you want to add that detail). Good luck! And I agree, this is the BEST pattern ever! Have fun! Anna

    It looks like you don’t use the extra strip of fabric on the back of your crotch opening; that’s certainly a simpler way of construction. Have you found that it causes any problems with the fit?Your instructions are very helpful. Thanks.
