I folded the watteline so, that one side was 0.6mm shorter than the other, this will prevent the watteline to form a ridge.
Next: Place the jacket wrong side up in front of you:
Turn over and sew with the watteline close to the feed dogs ( if your watteline is fuzzy try to lay some stabilzer that dissolves in water underneath)
Here's the final result with shoulderpads already installed. A big improvement or what do you think? Parting shot: believe it or not. Greebo loves to cuddle. This is the cat, my MIL thinks of as "the very shy one, that runs away everytime somebody looks at him"
