What do you do?
If the user manual for your machine doesn't cover this, you can always guess. Making mistakes isn't a big deal. It may be tedious but you can pick the thread out so you can start over with embroidering the pattern on your item. It's time consuming, but it's one way to learn what you need to know.
On the other hand, you can go online to an embroidery forum. Pull up a search engine and type in 'embroidery forum.' You can go to one of these bulletin board type websites to ask the questions that come up in your projects.
On an embroidery forum, you can get a lot of information and help for your embroidery projects. There will be information on what program to use if you decide to digitize your own embroidery pattern. There might even be information on companies to digitize your pattern for you.
Getting information from an embroidery forum may take awhile. The information is organized, but it's not going to have a table of contents. You can spend hours or even days getting to know your topic. You can even use the forums to make friends who have the same interests as you do. All that's required is regular posting to the forum itself.
If after reading, you still can't find the answer to your question, create an account and ask the question on the forum. As a general rule you want to make sure you are polite and ask your question nicely. If someone has experience with what you are asking, they will answer you.
As a general rule, an embroidery forum is one of the best places to get information on digital embroidery and embroidery machines. There is information on all the different type of embroidery machines, and information on different types of digitizing software.
You may even decide you want to look over the forums before you even buy your embroidery machine. Doing that, you can get information on the best machine to buy. Before you buy digitizing software, you will definitely want to look at the forums. In doing so, you may decide that digitizing your own pattern is not for you.
Embroidery forums are definitely one of the best ways for you to get to know your new hobby or business. I personally recomend www.digitizingtalk.com
