Selective die cutting Doily die

I was playing around with the doily die and trying to get areas of non die cut areas.
This is what I came up with.
I saw a similar reverse on pinterest and the woman wanted $5.00 for the video!
I am always up for a challenge, so after a few tries I managed to get this heart to remain solid. I am still trying other options and shapes.
Stayed tuned while I refine this technique. I did another one where I have only the heart die cut and there is a space around it.

Meanwhile I took the cut and placed it on deep gray card stock and pink craft foam base. Sending this to my daughter and hope I can re-create this again!
