Lu Lu,
You can post questions here if you need help. Lots of posters here with EMB machines and they are happy to share their knowledge. What machine do you have? What type of projects do you like?
I started EMB with a BL spirit about 4 years ago and was afraid of my machine. LOL. Last year I decided to get the Dream 2 and still learn new features. Last night, I messed up a block with color choices so made another block. Yes, all 27,000+ stitches again! The mistake will become a mug rug instead.
Classes were a great help. There are many different methods and techniques to use. You usually find your favorite tips. Other suggestions are to use your machine, read the manual and press those buttons to learn the features.
Many design vendors have tutorials for their projects.
Stabilizing and hooping can be problems with some projects. Get them right before you start the project. Don't cut corners. I may over-stabilize some projects but generally have decent results.
Please post your questions! Best wishes.
