1. There seems to be TWO ways of doing shirring: using elastic and pull it while sewing, OR using elastic threads in the bobbin. Which way is better? (clearly I think elastic threads is the easier way, but is the result better too?)
2. If using the elastic threads way, I put the fabric down with the RIGHT side facing UP, correct? And the fabric will shir automatically?
3. How much fabric would I need for shirring, in the case of complete shirring all around (like http://www.babyssb.co.jp/shopping/jumper/130247.html) and of partial shirring (i.e. just the bust part, like http://www.babyssb.co.jp/shopping/jumper/130243.html)? My measurements are 34" bust, 26/27" waist.
4. Any other tips?
Thanks for your help! ^^
