The Irish Crochet Thread used in the lace belonging to the County Cork Industrial Association Irish Lace Collection appears to be of a much finer quality than I have ever seen used in the more modern crochet pieces that I have come across. I could say “in the interest of research”, but really it was more out of curiosity, that I rang around a few different suppliers requesting their smallest crochet threads and hooks. A supplier in England, https://www.roseground.com/ appeared to be the only place I could find what was officially called a no. 100 crochet thread. (For anyone new to this, apparently the smaller the number describing the thread, the thicker the thread.) This may have been because the thread that arrived, which was a no. 100 thread, appears to be similar in size to standard sewing thread but with a mercerized finish so maybe I was asking the wrong question all along and should have referred to a sewing thread size. The crochet hooks that I received were size 0.35mm and 0.4mm and the lady on the phone said these were the smallest size she stocked. I was surprised at how fine they were, as they were similar to a fine sewing thread needle but with a hook on the end. If these were the size crochet hooks used, it would explain the similarity to needlepoint lace with the hooked end just making the work slightly faster and easier. However the fine point was not very strong as, after taking the above photo, I dropped the 0.35mm size and the fall of only 18inches to the floor bent the top part of the needle. This makes me wonder if the 0.35mm hook would not have been sturdy enough. The amount of work carried out making the lace would have been substantial and difficult so maybe they would have used the .4mm size and upwards. However, I can say for sure that the tightness of the stitching and fineness of the thread does indicate a finer needle though than is generally used now.

Very fine crochet thread found in the 1913 Lace Collection from the County Cork Industrial Association
To compare with the thread in the collection, some of which appeared to be left over from the workers and had been wrapped around some card, the main difference appeared to be the mercerized finish on the more recently made thread. Other than that, the modern thread size was similar to that used in the various crochet pieces from the collection and that which was on the card. For anyone who wants to try to replicate the pieces, perhaps start with just some ordinary sewing thread to see if you can replicate the fineness and complexity of the 1913 workers. I know I definitely would not have the patience but when I see the finished lace used in garments such as designer wedding dresses http://www.olwenbourke.com, it does make them so much more special. I hope you have enjoyed my journey of matching the past with the present in the world of Irish lace.
