Arrows: digits along an arrow must sum to the digit in the circle.
Carpets: digits along a carpet must repeat in the same order when it unrolls, starting from the dotted end (e.g: the carpet starting in R1C2 will unroll R2C3 in to R9C2).

This was tricky for me but I really enjoyed it! I ended up using colours, letters, and numbers. There was an x-wing that took a while for me to notice. I really liked the section where the arrows gradually narrow down the possible digits. Very satisfying to solve!

This was my first exposure to the carpet sudoku, and I greatly enjoyed this variant.

Super entertaining solve, I love how it all unravels (hehe) at the end!
