Nice to see you here. Welcome. Please read all the NOTES. They explain our policies, the laces we include, and how the software works. Join any groups that interest you. We do have one for RETICELLA and we include both embroidered reticella and needle lace reticell (geometric cutwork).
You might also enjoy http://stitchinfingers.ning.com another ning network which has a lot of embroiderers on it. Also free to join. Two of their groups might contain people who can help you find good books and instructions.
