Hmm, I wish I could be of some help here. When I started, I just ordered some Sublime Stitching patterns, slapped them on some dish towels, and got down to it
I don't know what I'm doing right/wrong, because I don't know anyone IRL who embroiders that can give me instructions. I don't know the names of the stitches I use, or what the best stitch for certain projects might be, I just do what looks right and doesn't fall apart. I did a lot of practicing on scrap fabric. I'm sure you can find an Embroidering for Dummies book, I personally learn better by doing. Good luck!
