Another sock?

I have been learning how to knit socks. The first time I cast on the cuff, I found that the sock was WAY too large, so I unraveled it and went down to fewer stitches to cast on. The cuff was knitted and looked too large again, but I kept working on the rest of the sock in stockinette stitch. It was still too large, so I decided I had better check my gauge. Since I was using knitting worsted in wool (washable), I found that I had about 6 stitches per inch after I had knitted a sample. I changed to a smaller needle size and a lot fewer stitches. It looks about right. Yeah! I hope it will work out because those socks are for my DH whose feet get really cold when he sleeps. Nothing more miserable than having cold feet when you sleep. Hopefully, I'll be able to take a photo of the second and third try. You'll see the difference. At least I can say that I am getting good at working with four needles and knitting the cuff and body of the sock. How will I do on the heel????
