If Stitch Delight had them, perhaps you can send an e-mail and inquire as to if they are still available...sometimes things are taken off sites to make room for new...they may still have them...and perhaps would sell one to you...
Windstar Embroidery.com. has various Chi Rho designs. Insert the Chi Rho in their search engine. Will look further, I too do ecclesiastical embroidery and have acquired many designs. Greetings, Patricia in SAfrica
Embroidery designs. com has a large selection of Chi Rho designs but not necessarily FSL
A beautiful design Krystyna; I had not come across it 'in my surfing'. Will keep looking and if successful, will let you know. Patricia
There are several lace pieces at secretsof.com, but I don't know if any of them will work for what you want.
Yes, Stitch Delight was the company that originally had them but they seem to be gone now.
