design needs

[celticdragonfly]

I am in need of a needlework pattern for a celtic knotwork/interlace heart. I'm expecting to use it for either cross-stitch or needlepoint - haven't quite decided yet. Can anyone help me find something? I have a mental image of about what I want, but haven't been able to find it yet. I'm willing to buy a book, IF it has a pattern. Not just a picture. Yes, I can convert a picture into a graph if I have to, but that's a pain. I'm designing something bigger that it will be part of.
