Antique bedspread motif

Found a photo of a beautiful bedspread on the internet.  Unfortunately, couldnt find a pattern or any information, but it is so precious that I feel it deserves a place in modern crochet. Probably an antique pattern originated from Italy that was handed down from one generation to the other. So this is a variation of that pattern as I made some minor changes to it.

Just leave a message in the  comments section if you need step by step photo's of the pattern. It is a unusual pattern and maybe somewhat sonfusing.

With nr 5 cotton thread and 2 mm crochet hook, ch 7. sl st in 1st chain to form ring.
1st round: 3 trebel cluster (ch 4 for 1st treble)  3 st on hook pull through to form cluster.5 ks, 7 more treble clusters in ring. End with 5 ch, sl st in 1st cluster.

2nd round:* 3 sc in 5ch sp, ch 11, sc in 7th ch from hook, sc in each of next 4 ch, 2sc in 5ch sp*  Repeat 7 more times. You will now have 8 "spikes" with loops.Work may curl, don't worry, it will auto=correct.
