Thank you Dokter Mom. Based upon your inputs, I'll may go back to the store and look at other patterns. I'm very petite, so I can't go with really busy patterns, but boxy shapes do me no favors either. I may need to rethink this. I picked the patterns as there aren't a lot of seams that break up the pinstripe in the front/back (some patterns have a lot seams that really don't go well with a dark pinstripe). The pinstripe is a dark blue matte with a dark blue sheen (not the traditional white pinstripe with blue). I think of it as pinstripe, as I need to be very careful to match up the pattern, but the pattern is very subtle to the eye.
I'm thinking about starting the project ver the upcoming holidays, after I get my MCAT score in Dec. THen, I'll have almost 8 months to work on it (which should be plenty of time, as I have the space in the basement to spread it out).
I will invest in more good interfacing, as I agree, it can be your best friend to get the right weight/right stiffness to go with the pattern. I also use really good thread, as I have a Bernina, which almost requires that fancy German thread, and the Bernina Rep told me I could ruin the machine if it don't use the good thread. I'm also splurging on really cool lining, which no one sees, but I'll know it is there.
Thinking and planning this is taking my mind off my Nov 7 MCAT.
