This was my first Sinclair pattern, my first sports bra and my first projector pattern so plenty of new experiences.
Firstly, the pattern is very well conceived and drafted and the instructions were nice and clear. I made a toile to check the size (US8, petite, regular bust, racer back) and tweaked it a bit.
I am not new to bra making but this was my first sports bra so it included some techniques I have not used before, such as reinforcing every seam with elastic and lining with power mesh to give it good support. I would say that it is not a beginner's project as some areas can be quite challenging, for instance the baguette approach to the straps (fine if you keep your wits about you!) and dealing with the increasing thickness of some areas by the time you have several layers of fabric, mesh and elastic to sew through. My finished bra is serviceable rather than beautiful, but I've learnt enough to make the next one better.
Finally, as this was the first time I have used a projector for sewing I can say that it made my life very easy. Everything worked fine (as long as I used Adobe Reader to open it) and I did not need to do anything except turn off the layers I didn't want, project and cut!
Thank you, Sinclair Patterns
