I have had Wild Ginger Pattern Master Boutique for a few years and have mixed feelings about it.
Pros:
1. It does help to have my measurements on file since I don't have someone around to help me measure most of the time.
2. Visual aids on taking measurements was a big help to the non-sewing buddy who helped me collect the measurements I needed.
3. You can alter patterns on line with snap and click feature.
4. Really tests your construction knowledge.
Cons:
1. Sloper styles available are limited and sometimes wont let me add certain style of sleeves or neck openings to styles I want.
2. Taping pattern pieces together can be cumbersome in small spaces, especially for dress and pants patterns.
3. Some pieces do not fit together well making garment construction, without directions, frustrating.
4. Altering pattern pieces on the screen is not easy. Bought the program to help me obtain fit when I made creative alterations - but that hasn't really happened yet.
5. I take longer to sew garments because I get frustrated with construction problems that I have to work through (means researching a solution, no direction sheet to refere to). Sadly, I find myself sewing less since I bought this program because it has become frustrating and disappointing.

Sadly, of the garments I have constructed using this program I would not say I am satisfied with the end result. Can not say it is all the fault of the program, this user will take some of the blame.

Thank you so much for this article and grid tool, it will be invaluable to all my design projects because of my disproportionate figure. Being a creative scientific type of person, this way of being able to calculate my best lengths, widths, angles, etc. helps to keep both sides of my brain working in harmony on a project.
Keep up the good work on inspiring and teaching! This article is just another reason I have to justify schlepping around my numerous volumes of Threads through all of our moves. I love you, the movers don't!
