I think most people are scared to do it because they have flashbacks to some kid in 5th grade whose mom hemmed his jeans. And they screamed “HIS MOM HEMMED HIS JEANS!”
Don’t be scared.
It’s way easy…just one straight line.
Awesome tutorial with pics here.
See? You can barely tell they’re hemmed.
This particular pair is for a customer at my sister’s store. Go see her if you want your own pair.
