Nothing to it - just stretch the lace over the wood frame backing and staple in the back, as tight as you can without ripping it.
The frame was from the dollar store, i just painted it dark purple. Don't forget to paint the wood backing, it'll show through the lace!
I actually found out that the scrap I used was part of my mom's engagement dress, so she thought it was cute that I framed it :)
(P.S. No, that wire is not coming from the frame, it's from my laptop. However, if you wish to add some fancy electrical parts, have fun with that xD)
