The best aspect about this software is that I can design my own pattern, then upload them into their library of ready designs so they are available when needed! It's also easy enough to use even if one has no previous experience with sewing or designing fashion items (although there may be tutorials in some languages). There isn't much as far as downsides go - but perhaps not having an option like Adobe Illustrator would help? Overall though really good at what we need/want from our product development tool. We're able create custom products which have been well received by clients who understand how important style matching will affect overall success / failure rates etc.
