There are two length options included in this pattern. Was created using DK yarn - but can be modified to use worsted (4). For traditional length (see pic of red cowl), uses around 100 yards in DK and just under 200 yards in worsted. Full length uses approximately 350 - 462 yards in DK and a little over 500 yards in full length if using worsted.

Always use an oversize hook. Example - for DK, I used and note 6.00 mm in the pattern. If your tension is tight, consider using a 6.5 mm. If using worsted, most call for 5 or 5.5 - so definitely use at least a 6 mm or 6.5. If tension is tight, consider a 7 mm. This item is meant to be loose.
