For those commenting on Mac Software-Cochenille has a native Mac OSX version and PatternMaker is CrossOver certified.

As for what to buy-my advice is to have a good idea of what your body type is and what you want the software to do. What level of computer skill or drafting skill is required to get what YOU want. Look at their user's groups and see what their users say.

Some of the companies have either a trial or a demo where you can input measurements-see if your measurements will draw a pattern that looks like it should! If they don't, see if you can find a user at a local sewing machine dealer that would be willing to run a pattern for you. Most people that like their software are more than willing to help. Also keep in mind that drafting software is like brands of sewing machines. People that use it get VERY attached to theirs!

I also work for one of the companies that was reviewed, and have used nothing but software for about the last decade!

Nice article!
