The steps below are the same as your pattern, however they also include photos of each step. I do hope this helps you in completing your gorgeous creations. xx
Take your largest embroidery (please note that for this tutorial I am using a fussy cut piece of fabric rather than an embroidery) and the largest set of frame hardware. Each set of hardware includes the black perspex frame, a thinner wooden frame, a cardboard insert piece, and a final cardboard backing piece which has 2 small holes.
If you wish to hang from a nail, take a length of strong string and thread this through the 2 holes in the cardboard backing piece. Tie the ends securely on the wrong side of the cardboard backing, ensuring there is enough slack for hanging but not too much that the string will be visible from the front.
