Hi Cartona,
I am happy to help. From one of my other books, Benardout "Care and Repair of Rugs and Carpets", he lists tools. For needles, he recommends Tapestry size 20 and 22, Straws size 2, 6 and 8 and Sharps size 6 and 8. Tapestry, Straws and Sharps are standard names for particular types of needles. I would have to look in Stone's book to see if he makes particular recommendations, but these have done for me so far. I got most of these needles from
http://colonialneedle.com/home.php in White Plains, NY. My one order was processed and shipped quickly, without any problems, so I don't have any problem mentioning them. Benardout's book is worthwhile and not very expensive. Unfortunately I don't remember where I bought it or I would let you know. Could have been Amazon, eBay or Abebooks.
Keep up the good work!
Bruce
