There are so many online tutorials now. They are so helpful. Recently, I was trying to become more familiar with entrelac knitting. So, off to YouTube.com I went. I found Planet Purl and found her tutorials to be very informative and she has a good way of teaching; nice closeups and few out-of-frame stitch demos.

To see all of her videos, click on "Uploads (86)" just above the first video on the left-hand side. YouTube's interface can be confusing.
Of course there are many more, but this is the most recent. I am so grateful for all the folks out there who are confident enough to upload demos to YouTube.
