Auto digitising is a very inferior way of producing embroidery designs. One would think that the program creators would have solved this but they have not yet. It is useful for someone who already knows how to digitize as a large amount of adjusting is often needed to fix the auto design.
Digitising is a skill that needs to be learned and sadly many people make the mistake of thinking that they can buy a digitizing program and use the auto programs to create fast designs for sale on the web. A great number of those people have virtually no experience in digitising and do not know the principals behind it and the many things that need to be considered when creating a design. All they can see is a business opportunity.
To my horror I have found out that there are many people who digitize and sell designs when they do not even have a machine to test sew with!! Nor have they stitched an embroidery design on any machine ever and know nothing about backing and pull compensation or even about embroidery. Most of these people sell their designs very cheaply. Buying such designs because they are cheap ends up being very costly because a large amount of them will sew out very badly and you may often waste a lot of fabric. There are also many people who do the same thing with manual digitising both of them think that what they see on the screen is what will sew out but this is not the case.
Manual digitising is far better. There is a lot to learn about embroidery and digitising but if you learn manual digitising you will have so much more control over your designs and you will not have to do so much adjusting and editing as you do when using auto programs.
if you are serious about digitising and you are concerned with quality and not just making a quick buck, it is a highly satisfying skill to learn.
Someone who digitises manually will plan every step of the design to ensure quality whether it is a small quick design or a highly detailed one. They will also have a knowledge of the actual embroidery stitching side because if you do not know embroidery and the way designs and stitch out then you certainly should not be digitising for sale as they both go hand in hand.
If you want to learn to digitise I highly recommend John Deers Book which is Available in my Amazon Affilliate Store Both in the UK and the US. John Deer is an expert digitiser and learned from childhood on the original old machines. This book gets to the point of all the many questions that do not seem to be answered anywhere else.
The cost of Embroidery designs on cards are very expensive and have copyright policies that do not allow you to use the designs on products for sale. Very good digitisers charge high prices because they work very hard and long hours producing quality designs for you instead of mass producing inferior designs cheaply. Always choose sites that state that their designs are manually digitised and most importantly TEST SEWN as they will sell good quality designs. Bear in mind that embroidery is not a cheap hobby and quality designs will be costly but cheap designs in the end are far more costly. I had my fair share of bad experiences with my journey through the maize of embroidery designs and eventually decided to learn how to digitise myself. A large amount of time and effort goes into digitising and it is hard work.
Nevertheless always test your design on a scrap piece of fabric first before sewing onto a garment no matter where you get it from. If possible use the same type of fabric as the item you intend to sew on because different fabrics can have different results.
