Double knitting is something I had never tried before, last weekend one of the very talented knitters in my Knitters Guild group ran a workshop on it so I had the chance to learn how to do it.
In double knitting you are knitting a double thickness of fabric. The way that you switch your yarns and stitches results in only the purl stitches (smooth looking stitches) showing on the outside of your work. It sounds complicated to get your head around and you cast on with 2 strands of yarn but treat them as one stitch which adds to the confusion. After the first few rows it starts to make sense. You can use this technique to make each side of the fabric a different colour the entire piece or you can twist your yarn colours around to form patterns within the piece. The result in a negative image of the pattern on the reverse side of the piece. In our workshop we worked off a chart to create a picture of a house. I only got the first half dozen or so rows done but I can see the picture starting to develop.
Prior to the workshop I had seen items done with the negative image in reverse and I really liked it but I had no idea what it was called or how to do it. I really like double knitting now that I have learnt how to do it. To be honest I am not going to finish the house, I used scrap yarn and will take it off my needles and return it to my scrap yarn bag. I do want to try this technique on a dishcloth or maybe get some 8 or 12 ply wool and make a hot pad trivet with it for the kitchen. It is very slow technique to work up in that you have to keep changing the yarn colours between your fingers and switching between knit and purl stitches. You have to really concrete on what you are doing so you don’t make a mistake in your pattern which means no auto knitting. I guess depending on the thickness of the yarn you use and how long you want to spend doing it you could make clothing other than scarves with the technique. I don’t think I would even have the attention span to do a scarf in it, a trivet I can handle.
