I want to make this shrug, and the pattern calls for aran (the creator used Lion Brand Cotton-Ease). I have some worsted weight merino, which I bought for no good reason other than the color was really pretty, and I'm wondering if it's an OK substitute. I tried researching online, and some say worsted and aran are practically the same, while others say aran is heavier.
You guys have always provided excellent advice in the past, so what say you? Can I substitute here?
