G6 crochet hook
4-6 skeins medium weight worsted yarn, stretchy
A tube top is an crochet project because it moves quickly from start to finish. Pair a basic tube top with jeans or a cute skirt for girls, or with a jacket and skirt for an older, more formal look. The scale of this tube top is 16-20 stitches per 4 inches using a G8 hook and a medium weight yarn. The pattern is intended for a young girl but using the cited scale, increase the pattern to fit any size.
Measure the bust of the intended wearer of the tube top by holding the end of a tape measure at the back between the shoulder blades and bringing the tape measure across the center bust and around to meet the starting end at the center back. Calculate how many stitches you need to wrap the finished tube top from center back to center back. With a G8 hook and medium weight yarn it takes 16 to 20 stitches to produce 4 inches of finished crocheted area. So if the bust measures 32 inches, divide 32 by 4, which equals 8. Multiply 8 by 16, which equals 128. Eight multiplied by 20 equals 160. That means you need between 128 and 160 stitches to reach from center back all the way around the upper body back to the center back.
Do your math and decide how many stitches to start with. Chain that many stitches. Hold the beginning of the chain at the center back and wrap it around the bust to double check the scale. Add or subtract stitches as necessary to circle the upper body comfortably, but tightly enough for the tube top to stay up securely.
Double crochet (dc) in the fourth chain from the hook and in each chain thereafter. Chain three and turn.
Skip the first dc. Dc in each dc to the end, chain three and turn.
Skip the first dc. Dc in each dc to the end, making the last dc in the top of the turning chain.
Repeat Step 5 until the piece is the desired length. Hold the work in progress up to the body often to gauge length. End by cutting the yarn 1 inch from the hook and pulling the cut length through the top of the last stitch. Pull to knot.
Bring the back edges together and slip or chain stitch the ends together for a back seam.
