How to Knit a Thong for a Man. Thongs are not just for women. They're for men too. The trick is knowing how to shape the front so as to keep the thong in place, and prevent anything interesting from slipping out. If you think the man in your life might look sexy in a knitted thong, there's only one way to test the theory.
Knit the Pouch
Check your gauge. To knit a thong using this number of stitches, you will need to knit 22 stitches by 40 rows into a 4-inch square. If your gauge is off, try switching needles or calculate how many stitches you must sew to get the proper lengths for this project.
Cast on 18 stitches and knit your first row.
Purl your second row, and decrease one stitch at the end of the second row and every fourth row thereafter until you are down to eight stitches.
Work in a stockinette stitch without decreasing for five more inches. Make sure you are on the right side of your piece at this point.
Increase six stitches, evenly spaced, across the next two rows. Now you have 20 stitches.
Wrap the second to last stitch in the next two rows.
Continue working by wrapping the third to last stitch in each row until you have only one stitch left.
Finish the pouch by continuing in stockinette stitch until the entire piece measures 10 to 11 inches long. Then bind off.
Finish Your Thong
Cut a 1-inch piece of elastic to the desired waist size and sew the ends together into a circle.
Cast on the appropriate number of stitches so that you will have a length equal to the length of the waistband.
Knit in the round until you have a rectangle that will wrap around and cover the elastic. One row more than two inches wide will do.
Sew the piece you just knitted around the waistband.
Attach the pouch of the thong to the waistband by sewing the front directly across from the back.
