Victorian Heart With Tatting

I took a lovely free square pattern and made three and then formed another heart the pattern is by a designer on Instagram called
_nu_rose

So below is the patter for he lovely, square
To which I encircled with more tatting.
Its beautiful and I like it but not interested in writing the outer side down for the inside was making 3 separate squares and lots of hiding ends.
