I really like the treble crochet stitch. I like all the loops. I like how tall the stitch is. I like the name. I just like it. I don't have a lot of upcoming projects that call for treble stitches, but maybe I'll do something to change that soon.
The Leisure Arts website doesn't have videos for how to do a treble crochet stitch in a chain. So here's your video for doing it in foundation stitches. I'm sure you'll manage. Remember when I said that once you figure out how to get the yarn through your loop you can do anything? I wasn't just being encouraging--it's kind of true.
Once you get to a point that you know how you like to hold your hook and yarn, and your brain doesn't freeze when your eyes send it a message like "ch 15, skip 2 st, sc into one-third of the parsecs for double think, etc.," you're well on your way to being a real-life crocheter! If you've been watching these videos, then you're probably qualified to just say "Yes." if you people ask if you crochet. No more of this "Oh, I can only chain/do a few stitches" business for you. You're definitely a Crocheter (yes, with a capital C!) now.
If you can single crochet into a chain, you can treble crochet into a chain. Stuff like this doesn't faze a Crocheter like you. Foundation stitches are a little bit trickier, though.
So aren't you lucky there's a video for that!? You are.
For the record, in case you don't want your brain to freak out: the treble crochet stitch appears as "TR" when abbreviated for patterns, and is sometimes called a "triple crochet stitch." Man, what do you plan to do with all this crocheting knowledge?
