Turtlenecks have a tendency to loose their shape over time. Rather than discarding them after they no longer look good, turtlenecks can be converted into a crew neck garment. The conversion process involves ripping open the seam attaching the collar to the body of the garment and resewing, reknitting or re-crocheting the edge into a crew neck.
Turn the garment inside out. Use the seam ripper to remove the stitching holding the collar to the body of the garment.
Measure 1 inch up from the bottom of the removed collar. Cut a 1 inch wide ring to serve as the new collar of the crew neck garment. The width of this ring can be adjusted based on your preference.
Fold the ring in half, bringing the two edges of the ring together. Pin the edges together to the inside of the garment forming a collar.
Sew the collar in place from the inside of the garment.
Turn the garment right-side out before you wear it.
The crew neck collar can also be knit or crocheted depending on the fabric used.
