This is a lesson for beginners. I will be assuming you have NEVER crocheted before in your life. Be patient with me if you already know some (or all) of these things.
Get a skein of yarn. Choose 100% acrylic, 4 ply. Nothing fancy. Nothing frilly and fluffy. Just a basic yarn. You can get into fancy and fluffy yarns later, once you feel confident in your skills.
After you have the skein ends ready, take the working end (shown to the right, above) and pull out a small pile of loose yarn. One rule to keep things running smoothly and peacefully is to KEEP IT LOOSEY-GOOSEY! :-) If you are constantly pulling and battling your yarn, you will fight for each and every stitch. Do you want to do that? No. It will be much easier to have beautiful and uniform work if you keep things loose.
So, pull a little pile of yarn out of the skein as you work. If you feel tension on your yarn as you work, pull out another little pile of yarn.
Be careful not to pull too large a pile of yarn, or it will tangle up and you will battle that! Just pull enough to keep from having tension on your yarn as you work.
Here is a reasonable pulled-out pile of yarn:
Now I must go and gather groceries! (The word Groceries will forever bring to mind the book Eat, Pray, Love. LOL!) And, so you go and do other things, too, and I will post the next lesson by late tonight. This brings me to ...
When you are not actively crocheting, you will want to store your project. Once you really FEEL the meditative and relaxation aspects of crocheting, you will want to take your crocheting everywhere you go! You will do it at lunch time. You will do it in doctor's office waiting rooms. You will crochet on planes and in cars (my younger sister gets car sick when crocheting in a moving car, so be aware of your own senses on this one). Get yourself a fun bag to tote your crocheting. I recommend a large nylon beach bag. If you have cats that will want to dislodge your efforts, maybe one with a top zipper or another way of closing it? Chose one that is big enough to store your upcoming skeins in the bottom, with your project on top of that. It is fun to see the skeins disappear and the project grow!
Next lesson: Chain stitch. The base of all crocheting.
