I really love my jeans long so when I had to hem a particularly long pair I hemmed them a bit long too. They became my favorite pair as they're super flared... I'm planning to make a pattern of them soon, based on the Jean-ius Craftsy class.
Hemming them long means I step on them quite a lot, so the hem now looks quite terrible as you can see above. This is how I plan to fix them. Supplies bought at the Bernina store in Zug... I'll be doing the repair by hand - as, alas, everything is still in storage.
