If you are interested in tying the original historic patterns then you will need the right materials. That is the case with anything like that. However if you just want to try this style of flies then go ahead and use what you have.
Some years ago I came across three spools of Pearsall's Gossamer No. 6b, the original silk for the Orange Partridge, One spool went to Oliver Edwards, one I sold on, the third I am still using, and yes it is on a Mattarelli bobbin.Now Pearsalls have started producing the shade again. I did get a good price for the spool I sold.Though not 477 prices. The last place I saw one for sale was Wharfdale Angling Classics, but beware it was priced at £35 (About $50). He might have some left.
