If you would like to get a copy of the altar cloth guidelines, call the temple department in Salt Lake : 801-240-3801.
The temple department also has a small variety of patterns that have been approved in the past that they will give you copies of if you request them.
A note of encouragement:
Anyone can make lace. It’s a skill more than a talent. It just takes practice. If you are working on a temple lace, send me a picture! I’d love to feature more LDS Lacemakers!
