Square Motif

I wanted to tat two square doilies for my bedside cabinets and so, instead of trawling through my pattern books, I thought I would design one.

This is what I have come up with, but knowing tatting, there is probably something out in tatland that is almost, if not exactly, the same.

I have used a split ring to climb out of the centre ring and also self closing mock rings as part of the design.

I would be greatful if any of my followers could tell me if they recognise this pattern as another designer's. If it isn't the same as anyone elses then I will write the pattern out for it and publish it as a freebie.

Thank you, in advance, for your help with my quest!
