I do not sell the threads or canvas needed for my designs, only the charts to stitch them. The charts specify what threads and canvas you will need for each of the colourways for each design. I am always willing to help UK customers source whatever threads and canvas are needed for a particular design in cases of difficulty. If you have a problem then use the contact page to send me a message and I will hopefully be able to point you in the right direction. I am sorry, but I am not able to offer this service to non-UK customers.
If you are lucky enough to live near a good needlework shop then please use them - although many shops in the UK do not keep some of the threads used in my designs. One of the reasons I love stitching canvaswork is the large range of threads you are able to use. There are two main online suppliers that I regularly use here in the UK.
West End Embroidery - this is my main source of the Mono canvas or Congress cloth that I use.
I have found both of these sites to offer an efficient, competitively priced service. I have used them all for several years and have found them all to be very helpful.
