Preferred Seam Allowances, Question for Book

[JM MacLachlan]

Hey all, so I'm coming down to the last wee bit of my book being finished.

So far, I have made all drafts with 1/4"( 7mm) seams however, I know the Rundschau mentions both 7mm and 1cm seams and Chaudhry does 3/8" (1cm) as well as other resources.

Would it behoove me to add at least one draft demonstrating the system with 1cm seams? I only ask as the distribution of measures needs to he taken into consideration and since this work is "international" and there are different standards. Or should I even bother as long as I give imperial/ metric considerations?

It would probably help.  Even some professionals in metric measuring countries might baulk at the imperial terms.

[JM MacLachlan]

Well Im already doing it dual measure systems. I'm just not sure how common 1cm seams are or if even "standard".

[Schneiderfrei]

I am not a professional, but I have not heard of 1 cm seams being used in industry, rather for homesewers.  All the German ones I've encountered are 0.75 cm.  And I thought 1/4 inch for British seams.  I would be very happy to be corrected in this though.

It seems that in German and some metric measuring countries use a 0.75mm seam allowance a lot (like some old   Soviet-Russian books sometimes). I've read a book originally Japanese using a 7mm seam. What I got in touch with more is that some Chinese books from 50s to 90s, ramdomly using 8mm, 1cm, or a 0.2 "Chinese market inch" (which is about 6.66mm) depends on discription of the different book.
