Another berry/bobble is the raspberry stitch:

So, there are popcorn, bobble, bramble, blackberry, trinity and raspberry stitches. Most sites seem to say popcorn and bobble are the same; bramble and trinity are the same, with maybe blackberry; then there is raspberry. I've seen instructions for smaller bobbles than the standard which probably fall into one of the other categories, but I've never compared the kinds of stitches to see if they differ.
Since I've started on this forum, I've learned a lot of stitches, found a lot of patterns and seen some gorgeous examples of knitting and/or crochet but haven't gotten anything else, such as knitting, accomplished.
If you want your knitting to resemble some crochet stitches, there are several cluster stitches such as daisy and cluster that do, along with some other faux crochet, knitting stitches stitches. I've found a couple that are on the member portion of knittingfool.com, but daisy instructions are available free and probably cluster too.
