If you have this professionally framed over stretcher bars, the knots won't affect the beauty of the picture. I have done this many times.

Thank you Cory. I am going to get this framed as it is a gift and I am relieved that putting in a knot won't hurt it any and the threads won't get loose. Appreciate your help very much.

I don't get it....I have always just woven the tail through finished stitches, as usual. Why are we you guys using knots on this?

Honestly, I have made knots many times when weaving wasn't possible. It has worked for me. Knots won't work if you put the picture on a sticky board. They will bump out the picture.

Thanks everyone for sending me suggestions on stitching my letters. Since I have just been teaching myself I always appreciate hearing back from more experienced stitchers and it looks like I a couple of options so I'll just see what works out when I get to that point. LR

Thanks Kristi for the tip on thread conversions...that is not anything I was aware of. LR
