People with SLRs always have this problem about losing or misplacing their lens caps, at least I do.
I did see friends losing their lens caps too.
It's like you do not know where to put or can't remember where you kept it.
So while I was browsing online I saw this solution to it!!
I didn't follow exactly the same and used my own "pattern"
It was fun hand sewing, measuring dimensions and such.
So here it is!
I got the cloth from Daiso at $2 and buttons from Spotlight
And maybe perhaps I should try knitting it and when it's successful I can start commissioning or sell it!
Earn some allowance or sort.
