Oh yeah, I checked the book again. It's "strip" (will edit previous posts later). My brain is so slow now that the more I think, the sleepier I become. Reading this explanation here is good enough so yeah.. I don't want to dwell too long on this lol. 

Anyway. It is finished! 

The colours are based on this mousepad (#3) I bought on Shopee end of January this year.

The original pattern is supposed to be like this (it's from this book):

I did make some modification though. I made it longer (extra one or two square-diamond thing). Was hoping to make it like the usual washable pillow case but it didn't look like what I expected at the back. So, I ended up using a button there. 

It's not perfect (pretty sure there's something wrong somewhere esp the back haha) but I love the colours. It works! Yes, I'm pretty proud of my chosen colours muahaha
