I'm going to fill in vertical patterns for the last three days soon. With today's pattern I'm finishing this series.
But I'm also uploading a picture that shows this pattern knitted with needles of different sizes and the effect of this. If you find a pattern too tight when doing the first swatch, use a needle one size larger, and vice versa.
The smallest swatch in the picture was knitted with 4 mm needles, the larger one with 5 mm, and the largest with 8 mm, which still makes a usable, very light and elastic fabric.
