The traditional method of weaving pictures is called tapestry weaving. The warp threads are set far enough apart for the weft to completely cover the warp.
It can be very slow as several different colours are often used in each row. However, it is a good way to start weaving as all that is needed is a picture frame, some strong cotton thread for the warp and coloured yarns for the weft
The method I teach could be called “lazy tapestry weaving”.! I use rigid heddle looms for teaching.
Landscapes and seascapes which do not have steep slopes are best. Photos of the Isles of Scilly are ideal.
A significant amount of the picture is woven with one shuttle for each row. I often use several strands of wool of varying hues to produce colour variations. I also use wool which has been dip dyed. I use meet and separate, a traditional tapestry technique using two or more shuttles, when slopes are needed.
I also use an inlay technique which I was taught by Riitta Sinkkonen Davies who specialises in weaving linen. I was particularly impressed by her scenes of the Pembrokeshire coast using inlaid handspun linen. I use a fine linen warp set at 12 threads per inch. A row of the fine linen is also woven between each row of coloured handspun silk or wool. The rows are further apart so the weaving part of the process is quicker.
I visit St Martins on the Isles of Scilly nearly every year. I was encouraged to weave pictures by Sue Lewington who paints wonderful watercolours of the islands. They are for sale in the North Farm Gallery which she used to own. Some of my pictures are based on her watercolours and some on photographs. The silk inlay technique seems good for representing the colours of the islands
