I tried and have one to donate
I made three in order from left to right. I think only the one on the right qualifies as spiky but, gosh, it only takes up half of the block. The other two lost most of their spikiness when I squared them up.
I tried but just can’t seem to get the hang of them and I had a lot of waste. I’ll try a few more for my QAL when I have a chance.
