TWO OPTIONS FOR CUSTOM JEANS TAKE A PATTERN THAT ALREADY EXISTS AND MODIFY IT • Pros: • Instructions + community exist • Avoid NIH syndrome • Cons: • Made for “generic human”; but every human is unique and making it fit is going to be time- consuming CREATE A PATTERN FROM SCRATCH • Pros: • Make exactly what we want • It’s been done before, in principle • Cons: • Requires skill to do well • Will likely still be painfully time- consuming
