This is a different answer than I provided my team, because now that I have thought about it a while, I realize that there are several garnishes that my clients don't necessarily pay for, but that I provide nevertheless.
1. Even small projects have a discovery process. this can be in the form of a fitting, discussion or design, but either way there is a good amount of time spent just clarifying the client's desires.
2. Most projects we complete do not get seen on the inside, but to me the inside finishing and cleanliness is a reflection of Chaos Works quality, so though almost none of our clients will ever see or notice the inside, clipping loose hanging threads, trimming away unnecessary seam allowance and generally keep the project clean of messy stitches is part of our standards. If something is stitched in the wrong place, it is taken out, we do not just stitch over it and if the fabric frays we assure to finish the edges in a way that preserves the longevity of the piece. When we are done with a piece it will look beautiful inside and out.
3. All projects are pressed and de-linted when completed. The sewing process can leave stray threads or wrinkle a project, so throughout a project we clean up and press the pieces as well as do a final press and clean-up for optimal client presentation.
4. I keep a notes and math record of every project we do, so that if the client ever wants to reproduce a project or has concerns about what was done I can go back to the record at any time to speak intellegently about the past project.
5. I complete a project review at the completion of every project to assure me and my team are growing from every project. Learning what went well and what we can do better. The client doesn't pay for this, it is simply part of the core beliefs of Chaos Works.
