Step 1: Cutting Pieces 1 & 2
There are 4 pieces to this shirt. Three in the front and one in the back.
Starting on the front top section fold over the shirt so you just see piece 1.
Cut the piece out 1/2" larger than the original. This shirt was tight in the arms so I extended the length of the armpit to the shoulder.
Flip piece 1 over and cut a copy. This is piece 2.
Step 2: Cutting Piece 3
Cut 1/2" wider around the bottom piece. This is piece 3. I lengthened it by a few inches because my sister is long waisted. If you are going to hem the shirt account for the added hem. I didn't hem the bottom because I didn't need to. The spandex will roll up a little around the bottom and keep from fraying
Step 3: Cutting Piece 4
Cut 1/2" wide around the shirt. Again I added a few inches to the length.
Step 4: Sewing the Top Front
Adjust the cross over on Pieces 1 & 2 to match the width (the top width) of Piece 3.
Pin Pieces 1 & 2 along the bottom. I place my pins perpendicular to the seam so I can sew right over them.
Sew Pieces 1 & 2 together across the bottom.
Step 5: Sewing the Top and Bottom Together
The sides of the fabric that you want to be the outside of the shirt should be facing each other as though it is inside out.
The bottom of Piece 1 & 2 should be even with the top of Piece 3.
Pin and sew Pieces together.
Step 6: Sewing the Front and the Back
Lay the front piece, with the inside of the fabric facing out..
Lay out the back piece, Piece 4 on top of the front piece. The inside of the fabric should be facing out.
Line them up.
Pin the shoulders and sides.
Sew shoulders and sides together.
Turn it right side out and it is complete!
Note that I did not finish the armholes, head opening or hem the bottom. With this fabric it was not necessary. If needed, surge or make a rolled seam with a traditional sewing machine on all the above areas.
