Two fat quarters
Here are your cutting measurements for the different sizes, I made a 6-12 month size. Since I used fat quarters, they aren't long enough, so I would cut two strips, for example if I was making the bottom tier for the 0-3 month size, I would cut two strips 3" x 19". So you just half the second number and make two strips (or just use longer fabric instead of fat quarters). This skirt is very versatile, so if you want it longer or shorter, just adjust the widths of your tiers, or add more tiers!
Top Tier - 3" x 21"
Middle - 2.5" x 28"
Bottom - 3" x 38"
Elastic - 13"
Top Tier - 3" x 23"
Middle - 2.5" x 30"
Bottom - 3" x 41"
Elastic - 14.5"
Top Tier - 3.5" x 24"
Middle - 3" x 32"
Bottom - 3.5" x 43"
Elastic - 16"
Step 1: Take the fabric that you want your middle layer to be and cut out your two strips (mine were 3x16).
Take your second fabric and cut out two strips for the top tier (mine were 3.5x12) and the bottom tier (mine were 3.5x 21.5).
and sew down both of the short sides on each. You now have three rings of fabric.
Layer the gathered edge of the bottom tier with the middle tier, right sides together and pin in place. Make sure your side seams match up.
Sew them together.
You're going to sew this in place, but as you do, fold under the raw edge 1/4" so that you have a nice clean edge that won't fray. Leave a 1" opening.
Pin them right sides together
Once you've gone all the way through and out the end, put your two ends of elastic stacked together and sew securely in place.
You're done! Enjoy this super quick and easy project.
