I made this for J and finished in 2 days. She loved it so much, she wore it for 4 days straight.
Here are the steps:
1 - Find a coloring pages off the internet that you would like to embroider and print it:
2 - Trace the chosen coloring page into a tear-away t-shirt stabilizer. This is paper-like and you can use it to trace your design onto. At this point, if the lines on the coloring page are thick, just pick either the outside or the inside line. You can also modify your embroidery by choosing not to trace complicated parts of the coloring page.
3 - lay out your stabilizer with the design onto a t-shirt and use an appropriate size embroidery hoop.
4 - start embroidering! You can have fun with which color floss to use, and even have your child's input at this stage.
