Hi guys! Welcome and I hope you enjoy knitting!
What is the best project?
there is no best... for me, I cast on and knitted the same scarf for about 3 years. Then one day I pulled out a simple sweater pattern with double strands and away I went. The scarf (knit every row, or garter knit) was good for getting the rhythm. The sweater, good for boosting my confidence. After the sweater (which sat in pieces for about 3 years because I was scared of sewing it up) I knitted a poncho. That was awesome for working on my tension. That went fast, relatively speaking. Then I spent one entire winter knitting slippers. I think I knitted 30 pairs! After that I went to socks... and so forth.
Is it good to have more than one at a time?
Personally I think so. I need to flip between projects. I need to have something that stretches my skills (so something I perceive as hard), then I like to have a small transportable project (scarf, socks, or hat), and I also like to have a larger mindless project (say a sweater with uncomplicated cables or miles of stockinette). Often I'll have just one more project on the go as well.
I take the smaller project with me when I have to go somewhere to wait (doctor's office, son's hockey game, etc). The larger mindless project is often my way of relaxing at the end of the day. Or I'll knit on it for about 20 mins and switch to the more complex project. I find that stabilizes myself and makes me ready for the challenge of the harder piece. And the extra project prevents boredom!
What to do with the last stitch?
If you are knitting flat, pull the cut end of the string through the loop and tighten, then weave the end back into the work of knitting.
If I'm knitting in the round, I'll keep the loop loose, thread the end on a needle into the loop, around the legs of the first look I knitted on that round, back into the last loop and tighten both equally. Then I reach under because there is often a small hole and make a horizontal stitch to fill in that hole and then weave my end back into the work.
I'm sure Amy has a video of this somewhere. I didn't watch those videos when I joined...
