I am using a 4mm needle for this because even though the pattern said 4.5mm I thought that the fabric was a bit too sloppy when I did the swatch. The smaller needle makes the stiches a little smaller and gives it a better drape rather than just floppy. I think that it is because the yarn has silk in it and is a little less 'fluffy' than an all wool yarn. I must add here that I do not normally swatch (I know I should) but I was so excited to try out the swatch pattern that I gave it a go and am glad I did because not only did I switch yarns I also corrected the needle size to give a better fabric - something I would not have done otherwise! I am sure there is a lesson to learn here but I have my hands over my ears and I am humming a tune!
Right now I am off to find some dispirable aspirin to gargle with as my throat feels like the lining has been stripped out - hope I can catch it before worse things come out!
