The bubble jumper pattern is made easily by combining the baby doll dress/top pattern with the bubble shorts pattern. 

Measurement

Jumper top to waist:  You'll need to take the top of the jumper measurement and measure down to the "waist" for the person you are making the jumper for.  Remember the waist is where the person likes to have their pants/shorts hang from and may not actually be the true waist. 

Jumper back pattern

Take your baby doll dress/top pattern (back pattern if separate) and bubble shorts back pattern and line them up as shown below.

Line up "fold" sides of patterns so they are straight together. 

Measure down the jumper top to waist measurement PLUS enough to finish top edge of jumper.  (Ex.  If you plan on doing a serged rolled hem at the top add 1/4" to your jumper top to waist measurement.  If you plan on doing a rolled hem with a sewing machine add 1/2" for two 1/4" folds).

Also, if you want to add a sash and give it a bubble over affect, you'll need to add another inch or two to the top to waist measurement in regards to where you place the bubble shorts pattern on top of the baby doll dress/top pattern. 

Pin patterns together. 

Place your pattern paper underneath the pinned together patterns lining up "fold" side with the left edge of pattern paper.

Trace around pinned together patterns onto pattern paper underneath.

Label pattern with "bubble jumper back" and "fold" as shown.

Place a yardstick at outer corners as shown.

Draw a line to connect.

Cut pattern out.

Jumper front pattern

Repeat procedure with the bubble shorts front pattern and baby doll dress/top pattern (front if separate) to make the bubble jumper front pattern.

Preparing the fabric

As explained in Chapter 1 you'll want to prepare your fabric before cutting. 

Cutting the fabric

Lay fabric out on fold.  Readjust according to size of bubble jumper paper patterns to get most from fabric.

Lay paper patterns on top of fabric.  Match "fold" side of paper pattern to folded side of fabric. 

Pin

Cut out one back and one front pattern piece out of the fabric.

Sewing

Pin front to back at side seams.

Sew front to back together at side seams, stitching at 5/8" from edge.

Finish edges with a zig-zag stitch or serge. 

At top raw edge, finish with a serged rolled hem (if preferred).

Tip:  Always start serging a rolled hem at a side seam. 

Or sew a rolled hem by using a sewing machine. Instructions are as follows:

Fold over 1/4" onto wrong side of fabric.  Press.   

Fold over another 1/4" and press again.

 Stitch with wrong side of fabric (facing up) as shown.

Special Notes & Tips on Shirring

Shirring the top

Place fabric under the foot with the right side of fabric facing up.

If garment has a rolled hem (done with a sewing machine) sew at left of stitching already sewn. Do not sew through three layers of fabric; (sew on one layer of fabric only). 

If you're sewing on a garment that has a serged rolled hem, start sewing about 1/4 - 3/8" away from the top. 

When row is completed, lock stitch, leave needle in fabric, lift foot up and pivot. 

Move over about 1/4" to start a new row.  

One can use foot as a guide. 

When sewing remember to pull fabric so it lays flat. 

Light weight fabric requires less rows of shirring for a nice pretty ruffle.  Try on garment after sewing two rows. The more rows sewn, the tighter the garment. 

To lock the stitch when finished, go back and forth a few times with a very short stitch length.  Pull on the elastic thread to make sure it is caught in the fabric.  If not, knot it up with another piece of elastic thread or finish off by tying it in a good knot by itself.  Cut hanging threads. 

Bubble hem

Finish the edge by serging

Or by doing a zig-zag stitch, fold over 1/4", press and sew. (Don't forget to take out the elastic sewing thread out of the bobbin and replace with regular thread). 

With elastic thread bobbin in machine, place garment under foot of sewing machine RIGHT SIDE FACING UP.  Sew elastic thread as before just to the left of the hem and through one layer of fabric only.   Sew one row of elastic thread.  This is my recommendation but 2 is also acceptable, and totally depends on the look desired.

Turn bubble jumper wrong side out.

With WRONG SIDE OUT, match up together the side seams on the bottom (hem) part of the jumper.

Locate the center of the front and back by pulling as shown:

Sewing crotch

Click here to finish with optional snap tape

Click here to finish without snap tape

Without snap tape

Pin together front and back at center, right sides together.

Place pins on either side of center pin, without pulling fabric taut, the crotch width of panties for the person you are making them for. 

Sew just to the left of elastic, starting with the first pin and stopping with the last.  Make sure to backstitch several times when starting and finishing stitching. 

Check to make sure leg openings are even.

Push seam over to one side and pin.

Sew so seam will lay flat.

With snap tape

Place two pins, one at the center front and one at the center back of jumper hem.

If you have pre-made snap tape cut about 4", and apply according to manufacturers directions. 

Once done you are

Fini!!!

If you opted to make your snap tape, directions on how to do this are followed.

Making your own snap tape

Cut two strips of matching bias tape 4" long.

Turn 1/4" over towards wrong side on each end of bias tape.  Press.

Place wrong side of snap tape to the right side of jumper matching up centers.

Pin centers together and on either side of bias tape while pulling fabric taut.  Do this for both the front and back of jumper.

Sew bias tape on.

Hand sew on six snaps according to manufacturers directions using a very strong thread. Do not use fishing line. 

Fini!!!
