The pattern uses 8/2 for warp and tabby and 8/4 for pattern. If you use 16/2 for warp and tabby, you could use 8/2 for pattern. If you use 16/2 for pattern, you would need a really fine thread for warp and tabby...or stick to 16/2 throughout and the pattern would just not be as dominant.

Sampling is definitely your friend.

Thanks Cheryl. That is very helpful. I think using 16/2 for both the warp and tabby, and 8/2 for the pattern will make the napkins lightweight enough. As you mentioned, sampling is key. I LOVE the weaving learning process.

Your very welcome...JST has sure upped my learning over the years!! I hope you photograph and share your napkins when you're all finished!!

Thank you for the response. I should follow Jane's advice and play with it - figure it out so I can use the lesson for other weaving in the future.
