No, I am over that. I tried for years to give solid input and 80% of the time get crap for it but here is a little something for you-
A bound seam more often than not has no functional purpose. It just looks "Nicer or "Cleaner". If you were to buy any pant worth their salt they wouldn't have bound ( taped) inseams. The taping or what ever you are using to bind the seam with will be pressed through at some point and will make the pant unattractive. In the case of dress trousers this should happen because it drives your tailor nuts having to remove it all before he starts altering. The only exception would be water proofing a seam but that's a whole different construction process.
Don't confuse yourself with "Serger". There are many types multi spool stitching machines that factories use and serve different purposes. Each machine has it's advantages and disadvantages. It all depends on what you are using the stitch for.
Is it strength? Is it flexibility or are you working with a particular fabric that needs to be sewn a particular way? Is it just faster and cheaper to do?
An example is a tee shirt- You don't want to single needle a tee shirt. I mean you could but why? Single needle isn't the best option. It's the worst. The tension and give isn't there. Now, you have to figure out what stitch you want to give the adequate strength and aesthetic. Are you going to sew ( serge) on side or both, inside or out. To many variables in your question.
There is always a fast an easy method of doing things and a more skilled and precise way of doing things. Those things are normally reflected in the price of the good being sold.
I hope this helps.
I am starting tee shirts and over dyes NOW this way stock and MTO, MTM will be here in time for spring and summer.
As someone who works retail, people are never satisfied with what you do and there will always be complainers. That said, I think I probably speak for a lot of your customers when I say you do what hardly anyone else in the industry does, and you do it very well. The level of transparency and communication is insane. Don't get discouraged by the haters. Looking forward to the overdyes and tshirts. I'm really tempted on the rose flannel MTO shirt too.......
