Yes be happy to. I have a tote bag full of old crochet books and magazines and had never seen it before. So easy. Just start with a chain stitch row for a foundation. Row 1 - single crochet, double crochet, single crochet, double crochet. Keep repeating til the end, chain 4 and turn then do the next row - do a single in a double and a double in a single keep repeating, do each row that way. With an alternating single and double the row will not be the same height. It’s a nice smooth look and is not quite so thick overall too, it seems like I use less yarn. What amazed me about seeing that lady was her blanket looked like nothing I have ever seen before. I crochet more than I knit by far. Not coordinated enough to use 2 needles LOL.
Well, it’s not the “Wattle Stitch” as I thought, but similar. I don’t know what the name of this stitch, as you described, would be. I’ll keep looking around & see if I can find a name for it - surely it has one! Just from what I know about crochet, I can see how this would make a nice crochet ‘fabric’.
I also crochet more than I knit. I’m working on my knitting, but I’m so slow .... takes me ‘forever’ to get anything done!
AHA! I think I’ve found a name for your stitch ... Griddle Stitch!

Start with an odd number of chains. In the second chain from hook, work a single crochet. In the next stitch, work a double crochet. Alternate across the whole row SC and DC. The last stitch you make should be a DC. Chain one and turn. Single crochet into the DC you just made from the previous row. Then, double crochet into the SC. Alternate again across the whole row. Always DC into SC. Always SC into DC.
