I love socks a lot because inshallah, it can really knit up fast and the projects are quite easy to do. Not a huge fan of gusset heel but trying out new heels- peasant heel and even fish lips ksis heel. Which is good. I hope I can learn to knit on DPN but for now just using circular needles.
Sweaters, since I enjoy the process of knitting more than the final product. I could spend months with just stockinette stitch and relax. I also have not yet mastered DPNs, maybe in the future :)
