The pattern is
rnd 1: ch 2, 8 sc in second ch from hook.
rnd 2: ch 3, sc in beg sc, (ch 3, sc in next sc) 7 times.
rnd 3: Sl st to ch-3 sp, ch 3, holding last loop of each trc on hook,
3 trc in beg ch 3 sp, yarn over hook, pull through all 4 loops on hook pull through all 4 loops on hook-beg 4 trc cluster mde, ch 5, * holding last loop on each trc on hook, 4 trc in next ch3 sp, yarn over hook, pull through all 5 loops on hook.
I know how to trc, but can't figure out what they want me to do by holding the last loop of each trc
