Neckline Alteration: Mock-neck to Square Neck!

I had these two shirts that I loved. The fabric was soft and comfortable and they fit just right with no pinching or pulling. I loved the band around the bottom. However, I didn’t love that they had mock turtlenecks. They look super cute when I wear them, but it’s just too hot where I live for me to be able to wear these shirts as much as I wanted to. For this reason I decided it was time to change the neckline. This is what I did.

Let’s Make it Square!

I wanted the neckline to match the shirt’s cuteness so I wanted to try a square neckline. I have seen a few other people do this too and I loved the idea. Luckily I have another pattern with a square neckline I could adjust to fit this shirt. I just used the facing portion of the square neck pattern. You could easily make your own if you don’t have a pattern to swap necklines with. Or simple trace a square neckline on the front of your shirt.

First things first!

I turned the shirt inside out and then cut off the mock-neck. Then I folded the shirt in half and adjusted the facing portion of the pattern to fit my shirt by folding the pattern a little. Once I had done that I traced the square part on to one side of the shirt and cut it out. Then I flipped that piece to the other side and cut it out.

I left the back of the shirt alone because it was already the right shape and size that I needed. It matched the facing almost perfectly. Only had to fold the pattern a little.

Neckline facing….

I used the adjusted facing pieces to cut out the front and back facings and iron some fusible interfacing onto them. After I interfaced them I sewed them together at the shoulder seams. Before I attached them to the square neckline though, I did a staystitch around the neckline so it wouldn’t stretch out and lose its shape. Then I pinned the facing to the neckline and sewed it at a ⅜ inch seam allowance.

Then I snipped into the front corners and notched the back curve. This would help the facing lay flat when I turned it to the inside. Once turned to the inside I pressed it in place with my iron and did a 1 inch stitch around it. Then I cut off the excess fabric on the inside.

Liked it so much, I did it again!

I tried it on and absolutely loved the change! I could tell right away that this was going to be worn so much more now. I immediately did the same thing to my long sleeve mustard colored shirt that had the mock-neck too!

I’ll put more information below about the patterns I used in this post. But you ca do this with almost any pattern you have in your stash.
