As I go I put a tiny dash of the chalk
This will not be within the finished garment area, mostly I end up cutting right though it
You can see the little dashes along the silk
When I am all finished marking all the edges of the pattern I cut using the dashes as my cutting line. I'm careful to cut smoothly and to remember to mark the sizes for hems and folded in button bands etc.
Normally I would use 1/2 seam allowances but I am using a Hong Kong finish on the seams of this light jacket and I need the extra to work with the edges. I cut the neck edges 1/2" as they will have a Mandarin collar and 1/2" is all I need.
I wouldn't be without this favorite tool!
