Edmar
We use Maria's book "The Art of Dimensional Embroidery" as a bible . It has colour photos explaining the threads, seven weights in 200 plus colours!! and all the stitches with lots of charts for you to develop your own embroidered pictures .
The kits all come with threads, instructions, printed fabric.
We do stock most of the threads and can order or match as appropriate .
We highly recommend trigger cloth to work on.
