This tam recipe, free online, is designed for scrap yarn. There’s a nifty bind-off/pick-up trick that lets you work the tam a bit at a time. There are also instructions for working evenly spaced decreases on any random number of stitches--a trick I call “order out of chaos.”

Note: if you printed this pattern off the web before 11-26-14, go back online and look again--there were two errors, now corrected. You can find where the errors were by looking for two different passages headed "addendum, 11-25-14"
