I'm a layers person. I live in a temperate climate and run cool, so almost always wear a sweater/cardigan/jacket over my top, and the thing I found with SWAP in the past was that actually there were not enough over layers, but I understand that the rules have to cater to a large group of people and lots don't wear an over layer apparently.
Jackets are also a pain to sew, and I know the jacket component stressed me out the most last year to the point that although shown in my pictures I did give the jacket away as the fit was just not quite right.
The matching print or stripe sounds quite a challenge. I am almost done on the recent stripe blouse and working with the stripes has been quite an eye opener for me and definitely requires some skill and attention.
I'm not sure I love the emphasis on embroidery/unusual closures and so on, but I can see its a bit more creative. I am a bit nervous of it though as it tends to lead me to bizarre and unwearable madness if I let the crafty side have too much reign and the clothes still need to be tasteful and wearable.
