You guys, I am SO excited to show you the Halloween costumes for my boys this year!

They are both completely obsessed with Teenage Mutant Ninja Turtles (did you catch my 5 year old’s TMNT birthday party last month?) so it was a no brainer what they dress up as.

And luckily they both like different turtles!

Normally I am a last minute type of gal getting these sorts of projects done.

This year my friend Amber, with Lotus Blossom Photography, was offering up mini photo shoots for children wearing their Halloween costumes.

I couldn’t pass it up!!

Normally Amber only shoots weddings, so when she offers to do family or kid shoots I JUMP on it! She’s awesome!

But the kicker?

The costumes had to be ready by October 5th! 

Dude, I was so on that.

Ready for the tutorial for these Teenage Mutant Ninja Turtle Costumes?

Be warned! This post is very photo heavy.

My boys love to watch the old TMNT cartoons that we have on DVD, so these costumes reflect those turtles, not the new version on television now.

I like the old school turtles better.

They are more colorful, and more reminiscent of my childhood.

I remember my brother being obsessed with them when we were little!

These were pretty much a cinch to make, even for a novice seamstress such as myself!

If you have any sewing experience at all you will be able to knock these out in no time.

Little to no sewing experience?

It will take you a little longer but I promise, if I can do it you can, too!

Supplies:

a pair of sweats

yellow flannel

polyfill

bandanna

roasting pan

brown spray paint

brown ribbon

cardstock

VELCRO® Brand Sticky Back fasteners

needle & thread

masks and weapons

Unfortunately for me, green sweats in toddler sizes don’t seem to exist.

Sooooo… I purchased some white ones and dyed them green with Rit Dye!

It was my first time using Rit Dye, but I loved it.

I used Kelly Green.

I should have left the sweats in the dye a bit longer as the color wasn’t as green as I’d hoped for, but they still came out great!

Be sure to follow all directions on the box.

Let’s start off with that muscle shirt, shall we?

You can’t have Teenage Mutant Ninja Turtle costumes without some muscles, and most of them seem to be on the chest!

You will need to make an oval out of the yellow flannel.

The size will be dependent on the size of your sweatshirt.

Measure the front of the sweatshirt to determine the size of the oval.

To cut the oval, fold the flannel in half lengthwise, draw the corners of the oval on the material with a disappearing ink pen, then cut the material to create the oval.

Note: You can hem the edges of the flannel at this point, but I chose not to since this is a costume and not something that will be worn under close scrutiny. 😉

Center the oval on the front of the sweatshirt and pin it in place.

Stitch three lines on the flannel: one up the center, and two horizontally across the length of the material.

This will create 6 “pockets” in the flannel and create the look of the turtle’s chest.

Stuff the “pockets” with polyfill.

Not too much, just enough to puff up the flannel.

Pin down the pockets and stitch around the oval.

Bam! Chest muscles for our turtles!

Next up, let’s look at the arm and leg bands.

I stitched these on so I wouldn’t have to manually tie them on every time the boys want to wear the costumes.

Because, let’s face it, these are going to be worn a TON for play, not just one day for Halloween!

I was able to use 1 bandanna to create ALL of the arm and leg bands for one turtle.

There is plenty left over to make a mask if you need to!

Cut 5 3-inch strips from the bandanna.

Fold over the edges to make faux hems.

Iron them down so they stay in place.

For the knee pads, make the center of the strip slightly wider than the ends.

Knee pads: Pin the bandanna strip to the sweatpants approximately where the knee would be when worn.

Sew the bandanna to the sweats, leaving a 2 inch gap in the back that is not sewn down.

Tie the excess material into a knot.

Elbow pads: Attach these bandanna strips exactly as you did the knee pads in the approximate area that your child’s elbows will be in the shirt.

Wrist bands: You will be able to use 1 strip of the bandanna to make both of the wrist bands.

Sew them on just above the hemline on the wrists of the sweatshirt.

I only stitched once around the base of the hemline.

Finally, you cannot be a turtle, much less a Ninja Turtle, without a turtle shell!

Lucky for me, I already had one done because I had used it as a prop for the TMNT birthday party.

I found a 2nd smaller roasting pan for my little Michelangelo to use.

As I stated in the party post, I first painted the pans with green acrylic paint followed by brown spray paint.

The application of the acrylic paint allows the better adhesion of the spray paint.

Now we need to make a belt.

I chose a wide brown ribbon to use.

It’s not flashy and seemed turtle-ish…

Using an X-Acto knife, I cut slits on either side of the shell about where a belt would go.

I made the slit just inside the rim and the same width as the ribbon.

Run the ribbon through the slits and around the outside of the roasting pan.

I also cut ~ 4 inches of ribbon and glued it near the top-inside of the roasting pan with hot glue.

I added a VELCRO® Brand strip to the top of the ribbon.

The matching VELCRO® Brand strip goes on the back of the sweatshirt.

This will keep the turtle shell from drooping while on.

Time for the belt buckle!

I cut two pieces of gray cardstock in a 3 inch circle.

also cut a piece of scrap cardboard in a 3 inch circle.

Make a cardboard sandwich and glue the 3 pieces together.

While that dries, cut out the initial of the turtle you are creating.

I used the same gray cardstock as the belt buckle.

I inked the initial with gray ink to make it just a shade darker.

Glue it to the front of the belt buckle.

Time to attach the belt to the buckle!

Fold one end of the ribbon over on itself and glue it together then glue it to the back of the belt buckle.

Add a VELCRO® Brand strip on top of the ribbon you just glued down.

Take the other end of the belt, fold it over and glue it together.

Add the other side of the VELCRO® Brand strip to the ribbon so that it fits with the first VELCRO® Brand strip.

Add a small VELCRO® Brand strip to the back of all of the ribbon.

The matching VELCRO® Brand strip will go on your Ninja Turtles belly so that the belt won’t droop while on.

And now we have our turtle shell and belt!

It’s nice and lightweight and won’t weigh our little turtles down.

I would say, depending on how much the sweats cost, you can make this outfit for ~$15 which is definitely cheaper than you can purchase the costume.

We did already have the masks and weapons since my son received them as birthday gifts last month.

The Teenage Mutant Ninja Turtle costumes could not have turned out any cuter!

My Leonardo is in love with his costume.

My Michelangelo would rather play with his Michelangelo toy than dress up like him, but I think the outfit is growing on him.

Hopefully by Halloween he’ll be ready to wear it for more than 20 minutes!

But either way, do they not look absolutely adorable together??

A HUGE thank you to Amber and Lotus Blossom Photography for allowing me to use these fantastic images of my boys in their costumes!

If you live in the Nashville area and are planning to get married, be sure to look her up!
