Finally had the time to make this super easy tutorial~! I'm sure you will be addicted to make your own detachable collars after this Kawaii D.I.Y. session~ hehehe :D
Possible output if you get crazy with your creativity! ^^v
You will be needing any cloth / piece of fabric (preferably 20 x 20 in), needle & thread, 1 1/2 A4 sized scratch paper / magazine sheet, hook and eye, deco / beads, studs (optional), ballpen..
'I forgot to include a pair of scissors and some pins in the photo btw)
The total width of your detachable collar should be around the size of 1 1/2 A4 sheet of paper or approx. 18 inches (long) :D
