Some one advised me to find a digitizer which sews a sample on same material as the client's actual order will be sewn on. Digitizers... do you do that?
Years ago we would sew on material just like or similar to the orders our clients had.... we could afford to as left chest designs could begin at $150. BUT we still had to edit if the client needed an edit. Our singlehead sewed differently than their machine (even today a singlehead (nomatter the brand)) will sew differently than a 6 or 12 or any other combo machine.
I believe it does not matter what we sew here in our office... it ONLY matters what happens at our client's place. So for us to do a sewout is pretty useless unless clients in general would agree that: "Oh yours looks good so it must be OUR problem" nope... that will never happen. Ours is a partnership and each and every order we have to work with a design to compensate for a different partner.
Your machine will be different, your operators will change, machine speeds, tensions on thread and bobbins, humidity effecting those as well, etc. hooping, on and on, each fabric . you could be using the wrong needle , ball vs sharp vs wedge, etc. using thinner 60wt thread or not.
