This came up a couple weeks ago, hope it answers your questions.

Congratulations on your retirement, MJ! Wow! I'm sew happy for you. A long time ago a friend sent this to me, I think it is from EmbroideryArts and maybe you can find it on their website. I have a pdf of it, but can't upload it here - bummer.

Actually, I went to Embroidery Arts, which specializes in monograms. Here is the link to some of their questions and answers, and probably on the site or other placement guidelines! Check it out when you can!

Try Embroidery library,sure I saw something there.

Good for you.... You will love being retired....at least I sure do.... still have a lot of things to do and people to see, it keeps me busy.

Way to go! Glad you are enjoying it - you'll probably find that you'll wonder how you managed to fit work into it all! lol
