Stitch Length

[BMW]

I currently have an embroidery business and will expand into making leather bags and purses.

Have been researching what machine would fit best. Will mainly be using 2 to 4 oz. leather.

Looking at Consew 227R, Juki 1508 and a Techsew 2700.

The Consew and Techsew only go up to a 5mm stitch length.

Any opinion if this is a long enough stitch for the weight of leather I plan on using?

Any opinions greatly appreciated

IMHO long stitches make things look cheap. 6 to 7 maybe 8 inches to the inch would look a lot better.

Stitch length IMHO depends on material, thread size, personal preference, style and your local markets preference. I.e. a .8 mm thick thread or 1 mm even needs a longer length than a .5 mm thick thread and so on. 8 spi on a saddle looks not so great as it might on a watch strap. Same goes for a Celtic or Norsk item versus an Italian designer belt...

For wallets I like around 3 mm long stitches and I'm using a tera 20 thread. On bags I prefer a longer stitch of 4 to 5 mm depending on the leather I'm using.

This being said, the conversion of metric stitch length to spi is as follows: 25.4 / X = Y and will result in

8 spi = 3,2 mm

7 spi = 3,6 mm

6 spi = 4,2 mm

5 spi = 5,0 mm

Thanks for the info guys.

My question is more technical in nature than aesthetic though.

My concern is the minimum requirement of stitch length needed to sew 2 to 4 oz leather. Does a 5mm max machine get it done?

Thanks again for the comments! Appreciate all of them.

I wouldn't want anything longer than 5 on a bag.in my opinion, you need big thread to make long stitches look right.
