I'm new here and am a fairly new knitter. I've made a couple of projects and love it! I want to start making Christmas stockings. I started using a pattern that only required size 6 straight needles and then you sew the seam together throughout the entire stocking. I recently bought a circular needle and would love to use that instead and make it so there is no seam. I haven't made stockings or socks before so I'm very new to this sort of knitting. I have a pattern that I'm using as a guideline but want to make changes such as the size, more decor, and circular needles instead of straight needles. I guess my questions are these:
1) Can I just start with a circular needle until I need the double pointed needles for the heel and toe? Do I need straight needles during any part of the stocking?
2) I haven't done any stockings or socks before. Can I use a general pattern for heels and toes but just add more knit stitches and rows to make it match the size of the stocking?
3) Am I being to ambitious in thinking I can tweek a pattern when I'm fairly new at this?
Anyway, any help would be appreciated. I have looked at a bunch of christmas stocking patterns. I didn't find any that I really liked and have wanted to create my own with the designs and colors I prefer. I already have the designs on graph paper and love the way it looks with the stocking I made but I want to make the stocking a continues circle than to have to make it flat then sew it at the seam. Seems that it would be sturdier that way. Thanks in advance for any help!
