Method 1: Simple Tank Top

Sewing Pattern 18 inch doll Tee Shirt by OHSEWKAT
  • Supplies Needed: Simple Sweet Tee pattern, ruler, knit fabric, fold over elastic (8.5 inches). Print out the Simple Tee Shirt pattern pieces- front and back. Do not cut them out. Always check the one inch box to make sure you printed correctly, even if you have used the pattern before.
  • Measure up 1/2 inch from CF and make a dot. Measure up the neckline seam line (dotted line) two inches, and make another dot. Connect these two dots with a tiny amount of curve. From the second dot, make a straight line down to the armsye corner. Cut out your new pattern piece.
  • Flip the front pattern piece over onto the back and trace the new armseye, extending the top edge (CB) up one half inch.
  • Cut out the two pieces from your fabric, with the front on the fold as before.

  • Fold each armseye in 1/4th inch and stitch in place. This fabric is a pair of girls’ leggings I bought new at Kohl’s. It’s got a lot of stretch to it so I used wonder tape and my walking foot to make the sewing easier.
  • With RST together, stitch the side seams.
  • Cut 8 inches of 1/2 inch fold over elastic. This will form the neckband, connecting the sides in the process. Find the center of your elastic and pin it to the right side of the center of the shirt. (Follow the instructions in the Simple Tee pattern for the elastic- start with wrong sides together, then flip to right side and topstitch.) . Leave a gap of 3/4 inch between front and backs for the shoulders.

  • Fold the elastic to the outside and top stitch in place. The ends of the elastic will hang off either end by about 1/2 inch. Steam the elastic if it stretched out when you sewed it.
  • Finish the back seams, trimming off excess elastic.
  • Fold up hem by 1/4th inch and stitch in place.
  • Try the top on your doll and attach the hook and loop tape to both back edges as directed by the pattern.

Method 2: Contrasting Trim

Another variation would be to sew the side seams first, and then either fold the armseyes in as one long seam, or even add fold over elastic to each side of the armseyes for more contrast. Then add the neck elastic to cover the edges. You will need about 6 1/2 inches per side of FOE plus 8 inches for the neck.

  • If you plan to use this method, add a little bit of a curve to the under arm portion of your pattern, so you won’t have such a severe “V” to add the elastic to. Cut 1/4 inch off the center front and the center back lines. (If you fail to do this, the top will be too wide. (Ask me how I know… you can cut the center line and add a seam to make it the right size, like I did. I then covered it with ricrac to hide the seam before adding the neckline elastic.)
  • Sew side seams and press open
  • Cut Fold Over Elastic to two 6 1/2 inch pieces. Following the method in the Simple Tee pattern, attach the wrong side of the elastic to the wrong side of your top, fold it over along the fold line, and topstitch from the right side.
  • Add the neckband in the same manner, with 8 inches of Fold Over Elastic. Start pinning at the middle of the top with the middle of the elastic and butt the FOE edges right next to each other, without a gap. Stitch as above and trim off any extra at the edges.
  • Finish the back edges and add hook and loop tape according to the pattern directions. Press up 1/4th inch at the hem and stitch.
