Yup how to identify stitches and combos from an image. This will get you started, the trick is to be able to recognize what stitches and combos look like to a point you can make he pattern in your head. This is a great technique for wanting to make needle knit patterns on the loom but don't want the hassle of literally translating the pattern from needle to loom. So lets get started.
This is a pattern above I have never published. It is an Easter Baby Cloche. So lets break down some elements in the photo.
This is come basic visual, but to get more fluent at this, constantly research, research, research, this gets you more knowledgable about what things look like. This skill is also beneficial taking elements from say one picture and add to elements of another picture to create a completely new pattern. This is what I use often. This is a great skill to have as a designer. So take this start if you are interested to gain your skill in making your own creations through elements you like from an image. Have fun.
