Thanks to everyone for the support!
The jacket is a fiasco, I do not have anough fabric to do it again. I had preshrunk both fabric and interfacing, however, I guess, some fabrics are just not meant to be fused.
Anyway, once the semester is over I 'll try it again, in a more spring-summery fabric, and hopefully it would work.
I have two completed projects (from before the jacker fiasco) I have to blog about (pants and a top) but have to take pictures first.
Thanks again to everyone for the support.
I have a question... If I am to use sew-in interfacing, what type do I have to buy? Specifically, what do you use if you are using light- to medium weight fabric? Do you still use Hymo? If yes, which parts do you apply to?
