I am still uncertain on exactly what type and what colours of thread I am going to use for the main blanketing of the large piece. One of the insights that I have mulled over now... is that I have some really beautiful specialist artisan dyed threads that takes measurable time to prepare ..... which I don't mind.. but would be best set aside for the floral and plant work. Plus the technique I would have to use on some of the samples would be too thick for what I have in mind.
I am coming round to the opinion that I need a reliable thread that will be problem free for the background colour and shading as there will be a lot of area to cover with the machine... the rare dyed threads from these specialist dyers can be applied for the botanicals.....so with that in mind I am now going over all types of thread
