I'm kicking myself for not bookmarking the site...but it was so EASY i didn't bother. It was a clever NO CUT framed square/square in square tutorial. She took a 10" (layer cake) and a 5" (charm)...centered the 5" square on the 10" square - face up - folded the 2 sides in so that the fold was along the edge of the 5" square - pressed and stitched...then did the same with the other 2 sides.
SOMEONE on the Board will know where that Tute is.....i'll keep looking....cuz i thought it was GREAT for a quick and easy method.
