Some digitizers will include a copy of the design image in the same file as the stitch chart where as others include the image in a separate file. Here is an example of a stitch chart and the design.
The first step, highlighted in green, is your positioning stitch. Your machine will stitch this outline onto your shirt. This shows you the exact placement for your fabric. Once the position stitch has stopped, you will place your fabric on this area. Be sure to cover the entire stitched area.
Step 2 is your tack down stitch. This stitch tacks down your fabric to the area. Once your machine has completed this step, remove your hoop from the machine (do not un-hoop the item being embroidered) and trim the excess fabric from around the stitched area. Be careful not to trim any of the stitches but get close enough for a clean stitch out.
You will repeat steps 1 and 2 for steps 3 and 4. For this design, steps 3 and 4 are the placement and tack down steps for the crab's body. If your design has more than one two fabrics, you will repeat steps one and two until all fabric pieces have been added.
Now that all your fabric pieces are complete, the final steps are to add the satin stitches, which covers the outline stitches, and any accents such as the facial features of the crab.
Once your design is finished, it should look like the photo below.
