But they're all a bit different, so here's my version. Reinventing the wheel so to speak. Most of the ones I've seen have solid petals. Mine is made of chain loops. I have no idea if that's good or bad. :)
plastic net scrubber
size G crochet hook
ss= slip stitch
sc= single crochet
hdc= half double crochet
poking the crochet hook through the scrubbie at the circumference and making sure to catch enough of the net to have a secure attachment, sc around the outside edge, evenly spacing your stitches and joining with a ss when you finish the circuit.
*hdc in the next 4sc. hdc twice in the next sc* repeat *to * all the way around. ss together
(note: depending on how many sc you ended up with you may end in the middle of a repeat, so long as the round will lay somewhat flat and it joins up, you'll be fine)
the "petals" are made of chains and you'll have to turn the scrubbie this way and that to form them, but so long as they loop and attach at the right points the flower will look right.
Chain 10 skip one hdc and ss into the next hdc
chain 10 and ss into the skipped hdc (from back to front)
*chain 10 skip ahead past the last chain and one hdc and ss in the next hdc
chain 10 ss back into the skipped hdc*
repeat from * to * all the way around.
when you get to the first chain ss to last hdc finish off and weave in ends.
