How to make baby bloomers – free pattern and step-by-step sewing tutorial

Before you dive in, make sure to wash and press your fabric. Pre-washing helps prevent shrinkage later, and ironing makes it way easier to cut and sew accurately.

Step 1 – Cut your fabric pieces

First things first, grab your fabric and fold it in half.

Place the free baby bloomers pattern on the fold and cut out two identical pieces. You’ll end up with a front and a back piece – they’re the same shape in this pattern, which makes things super easy.

Here’s what your fabric should look like once it’s cut!

Step 2 – Sew the front and back rise seams

Next up, take both fabric pieces and pin them together, right sides facing each other (pretty sides touching).

Sew along the curved edges – that’s the front and back rise – using a 3/8″ seam allowance.

Don’t forget to backstitch at the start and end to keep those seams strong.

To keep things neat and avoid fraying, finish the raw edges with a zig-zag stitch or run them through your serger if you have one.

Step 3 – Sew the inseam (inside leg seam)

Now comes the slightly magical part – it’s time to shape the bloomers!

Open up your pieces and rearrange the fabric so the crotch area is lined up in the middle, and the two leg holes are at either side (like a little U-shape).

Pin and sew the inseam from one leg to the other, again using a 3/8″ seam allowance.

Backstitch at both ends, then finish the raw edge just like before with a zig-zag stitch or serger.

Step 4 – Finish the raw edges

Time to tidy things up a bit!

You’ll want to finish the raw edges of the waistband and both leg openings so they don’t fray. If you have a serger, great – just zip along those edges.

No serger? No stress. Just use an overlock stitch or even a basic zig-zag stitch on your regular sewing machine. It works just fine!

Quick tip: Pay attention to the way you’re pressing your seams – it makes a difference in how neat everything looks. (I pressed mine a little wonky in the pic, but hey, it’s handmade, right?)

Step 5 – Make the elastic casings

Now let’s turn those bloomers into wearable magic!

Start by folding the waistband to the wrong side of the fabric by about 1 1/4 inches, then pin it in place. Do the same for the legs – fold each leg opening under about 3/4 inch and pin all the way around.

Next, sew along the folded edges to create casings for the elastic – but don’t forget to leave a small gap on each one so you can thread the elastic through!

Grab a safety pin and use it to feed the elastic through each casing (this part is oddly satisfying). Just make sure the elastic doesn’t twist inside – smooth it out as you go.

Once the elastic is all the way through, overlap the ends by about 1/2 inch and sew them together securely. Then close up the openings in your casings with a few final stitches.

Here’s what I used for my size 0–3 month bloomers:

• Waistband: 1 piece of 1-inch wide elastic, 15–16 inches long
• Legs: 2 pieces of 1/2-inch wide elastic, each 7 inches long

And that’s it – your adorable homemade baby bloomers with elastic waistband and leg openings are done! Turn them right side out, give them a little press if needed, and admire your cute, squishy creation.

Aren’t they just the sweetest?
