Cottesloe Sewalong // elastic insertion for all views

Cottesloe elastic insertion all views

We’re in the home stretch with our Cottesloe swimsuits, friends! Today we are going to insert the elastic in all views of our suits. And if you are making view A, B, or C, this is actually your last and final step! Woo-hoo!

Like I said, inserting the elastic is the same for all views, but I’ll be showing it to you on View A. I’ll sneak in a few photos of what it looks like on bikini view C, though! And if you’re making the low back View A with ties, make sure you stick around until the end so I can show you how to finish up those ties once the elastic is done.

OK, let’s do it!

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsOnce you’ve cut all of your 1/4″ elastic lengths according to the measurements provided in the CUT section of the instructions (elastic lengths are different for all views, so make sure you cut the right ones), you will need to divide your neckline elastic into sections according to Neckline Allocation measurements in the ELASTIC INSERTION section .

We’re going to use the Front Neckline measurement to do this, and I’ll break down how to below.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsStart from one end of your elastic, this end will be your left shoulder. From the Left Shoulder, use your Front Neckline measurement from the chart above to mark the length of your entire front neck – the new mark will be your Right Shoulder.

The length in between your left and right shoulder is your entire front neckline.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsThe remaining section of elastic beyond the Right Shoulder, is your Back Neckline. The opposite end of the elastic will also meet at the Left Shoulder.

Divide the Back Neckline in half, marking halfway between the Right Shoulder and second Left Shoulder. This is your Center Back.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsPlace your swimsuit in front of you with the wrong side facing out (you may or may not have a lining or shelf bra. It’s all treated as one fabric at this point).

On the wrong side if the fabric, Pin the (original) Left shoulder of the elastic to the left shoulder of the swimsuit. Line it right up along the edge of the neckline.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsOverlap the elastic slightly at the left shoulder.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsLet’s start with the armholes. Divide the armholes into quarters, as well – the shoulder seam, side seam, and half way between the two on front and back.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsNow also divide your leg openings into quarters – the side seam, crotch seam, and half way between on both front and back.

Divide the elastics into quarters, and divide the garment edges into quarters.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen Patterns how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsPin them in the exact same method, starting at a side seam, matching up the quarter marks, and overlapping slightly.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen Patterns how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsTime to sew your elastic to your swimsuit with a zig zag stitch. As you sew, the edge of the elastic should line up with the very edge of the fabric.

You will also need to stretch the elastic as you sew so that the elastic and fabric are aligned.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsSew your zig zag stitch directly down the center of the elastic.

The elastic will be sandwiched in between the fabric now. Pin in place if needed.

This time right up against the raw edge. Again, stretching as needed as you go. This will enclose the elastic.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsYou will see two rows of zig zag stitching form the inside, but only one row from the outside.

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsRepeat the same process for the armholes and leg openings.

Then you will have two rows of straight stitching from the outside and zig zag along the inside.

You would have to sew this step form the right side of the fabric, though, so make sure you are catching the edge of the elastic on the inside as you go.

// FINISHING VIEW A TIES //

how to sew the elastic in the Cottsloe swimsuit by Megan Nielsen PatternsOnce all the elastic is done, you can now secure the ties on View A to the back neckline.

Turn your swimsuit inside out with the back facing you.

Hi, just received my fabric(online), it is Polyamide, the stretch just makes your measurement on the pattern, I was wondering if I should go up a size? Would really appreciate your help, looking forward to making Cottesloe.

This sew along has been so helpful for me as I make my first ever swimsuit! Thank you! I’m having some issues getting the elastic to cup my underbutt. I sewed up the size 20 bottoms with the proper leg elastic length according to your table. It was gaping pretty bad so I unpicked and cut out 3 inches of the elastic, stretching the elastic really good as I sewed . I sewed it up again and it’s gaping a little less but still gaping. It looks great everywhere else, except the bottom part of my bum. The size 20 fits my stomach and hips well, but I think my butt isn’t full enough to fill it out so perhaps I need to size down on the back piece? I also considered taking a little out of the back piece on the crotch and side seam.. I don’t know.. do you have any suggestions? Thanks!

I am also having an issue with the elastic being very loose in the butt region! I’m on my second Cottesloe and I can already see where I line up the elastic to the quarter markings that the front leg openings will have decent tension, but there is no tension on the back leg openings. I guess I will just try to maintain the same tension for the elastic for the front and the back leg openings, and cut off the excess, unless I hear back with another suggestion. Thanks.

I bought 6mm birch plastic clear elastic and I’m worried it might be the wrong thing to use? It seems very thin. What do you think?
