1. Cut each doily in half.
2. Fold up about ¾” from the flat edge.
3. Mark center by folding the piece in half side to side.
4. Fold up each side at a 45 degree angle so that it makes a pie shape.
5. Slide over the corner of your photo.
NOTE: if you look closely at the photo you will see that two corners have an open lace while the other two have a white area at the point of the corner. This is determined by which side of the inside folds you place the photo in.
You can buy acid free doilies.
