The first step is to look at the lace and find the motif you want to use it might mean a bit of trial and error but that's the way it's done.
Next step is to place some cut motifs on the spot where they are to be living to see if you want to have a centre or if you want the motifs to be random.
Once that decision is made cut a few more and add them to ones already placed try them in different arrangements eventually they will "click" and look like they belong!
Continue in this manner on one side only staying the motifs with some pins allowing you to make changes if necessary.
Finally, when one side is completed it's time to start on the other side! Now you get to do the whole process all over again only it's a mirror image of the first side. To make it easier start at one edge by removing a motif turn it upside down and find the matching one. Replace the first one in it's original position and place the second one in the same place on the other side as you see in the pictures below.
When the area is covered you can baste the motifs down before finishing by hand.
Once the lace appliques are all basted then using the same colour thread stitch them in place with invisible stitches.
The end result is so worth the effort! I usually teach technique classes at the Creativ Festival and the lace one is a favourite especially when I teach it wearing and evening gown LOL!
