Print the paper pattern, piece together with tape as per the instructions, and then cut around the black lines to make the bloomer pattern in your desired size. Fold the fabric in half to cut two bloomer pieces at once.
You should now have two bloomer pattern pieces. Cut the following for your elastic:
Size 0 - 6 months: Cut one 16" x 3/4" piece (waistband) and two 8-1/2" pieces (leg band).
Size 6 - 12 months: Cut one 17" x 1/4" piece (waistband) and two 9-1/4" pieces (leg band).
Pin one leg band elastic piece to the bottom of one of the bloomer pieces. Pin the upper edge of the fold-over elastic to the bottom edge of the bloomer on the wrong side of fabric. Pin the middle of the elastic to the middle of the bottom of the bloomer, and pin the sides of the elastic to the side edges of the bloomer. As you can see, the elastic is much shorter than the bloomer bottom.
Starting at one edge of the bottom of the bloomer, use a straight stitch to sew the elastic to the fabric. Pull the elastic as you sew so that it is the same length as the bloomer. The fabric edge should go to the middle of the elastic. Sew until you reach the other end of the bloomer; remove the pins as you sew.
Place the bloomer pieces right sides together, matching up all side edges. Pin the curved front and back seams together, and sew using a 1/2 inch seam allowance. Finish seam if desired with a serger, zigzag stitch or pinking shears.
Turn the bloomers so that the front and back seams are on the top and bottom, and press. Pin the bottom leg seam, still with right sides together, and sew using a 1/2 inch seam allowance. Finish seam if desired with a serger, zigzag stitch or pinking shears.
Overlap the ends of the waistband elastic by 1/2 inch. Pin the overlapped ends along the top edge of the back seam on the bloomers, on the wrong side of the fabric. Pin the elastic in various places around the top of the bloomers, such as the front seam and sides.
Attach the waistband in the same manner as you did the leg bands. Start at the back of the overlapped elastic; sew with a straight stitch, pulling the elastic as you go so that it is the same length as the bloomers. Continue until you make it all the way around the waistband.
And you are done! Put them on a clothesline to make an adorable baby shower gift, or match them up with a pretty store-bought dress or make your own accompanying dress. The perfect craft to make for baby, these handmade bloomers will make every new mom smile.
