You will need 2-1/4 yards of fabric and a D-ring set for the neck tie. If you want a contrasting pocket and ties, use a different fabric 3/4 yards in length for those pieces. You will also need a bodkin to turn the apron neck tie and waist ties, such as the Dritz Ezy-Pull Bodkin, although there are many manufacturers available.
The photo, above, shows half the pattern for the Kangaroo Pocket apron. The long, straight side of the pattern will be placed on the fold of fabric as described below to make the apron pieces. The long side of the pattern is 34-inches long. The top of the bodice is 6 inches wide on the pattern. The armhole is gently curved from the end of the bodice top to a point 10-inches down on the bodice. (The apron waist ties will be stitched in place at this point at the bottom of the armhole curve along the side of the apron.) Sixteen inches from the top, the pattern is marked with a double line where the pocket will be placed on the apron. The pattern is 13-inches wide at this point, and the pocket is 18-inches deep from the top to the bottom of the apron. The pattern is gently curved along the outside of the apron bottom.
Draw the pattern and cut two copies from tissue paper. Cut one copy of the pattern apart across the double horizontal line that marks the top of the pocket, creating a separate pattern for the pocket and for a facing for the bodice.
Fold one-yard length of fabric over 13-inches lengthwise and place the apron pattern on the fold. Cut one. Note: You must add one inch to the top of the pocket and one inch to the bottom of the bodice facing when cutting -- do not cut these pieces without checking to make sure you have added this length to both pieces. Place the apron bodice facing on the fold. Cut this piece out, adding fabric for a hem at the bottom of 3/4-inch. Place the pattern for the pocket on the fold. Cut out the apron pocket, adding 3/4-inch to the top of pocket for a hem. Cut three 3-inch wide strips across the entire width of the fabric making strips three-inches wide and about 42-inches long.
Bodice facing: turn up 1/4-inch on the bottom of the bodice facing and press. Turn up again another 1/4-inch and press to create a hem. Machine stitch hem.
Pocket: do the same for the hem at the top of the pocket, and machine stitch with a plain or decorative stitch.
Ties: Fold each tie RST (right sides together) lengthwise and press. Stitch along entire length of each tie, using a 1/4-inch seam allowance and closing one end of the tube by tapering the seam to a point. For each tie, trim seam allowance at the point, and using a bodkin, turn the tie right-side-out, and press. Pick one of the ties to use as the neck tie, and cut a three-inch piece from the NON-pointed end.
Fold the three-inch tube of fabric in half, enclosing the two D-rings inside the fold. (I used one circular ring instead of a D-ring set, which works okay, too, but D-rings are nicer.) Pin the folded tube with the D-rings inside to the right side of the top of the apron, 5/8-inch from the edge of the side armhole, with the raw edges toward the top edge of the apron bodice.

On the right side of the fabric, pin the raw edge end of the remainder of the neck tie to the other side of the top of the apron, 5/8-inch from the side of the bodice, with raw edges at the top, and the finished tail of the neck tie hanging free.

Pin the kangaroo pocket to the WRONG SIde of the apron with the WRONG side of the pocket facing up. In other words, pin the right side of the pocket to the wrong side of the apron.
Seam the pocket to the apron using a 5/8-inch seam allowance around the entire bottom of the apron. Clip curves. Turn the pocket to the right side of the apron. Press seam.
Pin each waist tie to the right side of the apron at the base of the armhole curve with the raw edges of the tie even with the outside edge of the apron.

Pin each side of the bodice-facing to the bodice, right sides together, enclosing the ends of the waist ties. Stitch each bodice side to bodice-facing side using a 5/8-inch seam allowance. Turn and press. If desired, topstich all around perimeter of the apron.
Measure 8 inches in from the side of the apron and draw a vertical line from the top of the apron pocket to the bottom of the apron. Topstitch along this line, to make a divider on the pocket. Repeat for the other side of the pocket, making a three section pocket for the apron. Pull the neck tie through the D-rings to adjust the neck tie length.
Note about sizing: although this apron adjusts easily to any size, if you wish you may easily reduce the size of this apron by cutting one or two inches from the long straight edge of the pattern that goes along the fold of your fabric. To shorten, simply reduce the length of your pattern along the bottom by one or two inches, then round off the curve of your new length.
