First briefing looks good. I can perform only semantyc check, ofcourse.
Several notes:
1. Alexandra Akimova and Sasha are two different people? (Sasha is a short form of Alexandra)
2. FYI, "Irina" is a full form. Common short form is "Ira" (also there are heap of various short forms, but I'd not recommend to use them in a foreign language, correct usage of them is quite delicate and depends on a context of usage, but if you need I can tell you all). But it's OK to use both these forms in any context.
3. If the character "was never good at stitching", it should not prevent her to try, it only takes more time. I hope later she'll find the time. Or ask somebody for. The somebody most likely will take a chocolate for it.
