How to reclaim yarn from second hand sweaters.
If you want to reclaim yarn from sweaters, you need to find those that don't have seams that were sewn together with regular thread. These will produce many short peices of yarn. First, remove the tag without cutting the yarn; carefull cut the thread attaching the tag to the sweater. Find where the collar is attached to the sweater and start there. Try to find the seam that attaches the two and start at one end and keep unraveling!
