What do you like?
I love making hats and gloves, and I like designing sweaters. But you do you.
One thing I would suggest is that you go through your wool stash and sort it by brand, name and dye lot, e.g., Red Heart, Supersavers Solid Aran, 234 Saffron . Once you know how many balls you have in each, you’ll know the approximate yardage, e.g., 5 balls at 364 yards(333 meters) per ball = 1,820yds (1,665m).
Then, with that information, you can go to Ravelry and look for patterns that use up to 1,820yds (1,665m) of Aran weight yarn:
1,706 pages with 25 patterns per page.
Alternately, you can search for Red Heart Supersavers Aran yarn:
You can reduce the hits on your search, such as only lace patterns, only adults’ patterns, only Icelandic patterns, etc., etc.:
But it’s a good idea to know what yarn you’ve got before you wade in and find the One Perfect Pattern – and then realise you don’t have the right yarnweight or yardage.
Just, ya know, don’t go knit-crazy with your cabin-crazy…
