You will need
Buy your jump rings in bulk - you can't have too many for this one. I got a pack of 100.
ModerateI have no reason to lie here, this DIY did have its fiddly moments, although I wouldn't call it difficult.
TimeA full day - 6 or so hours, I think - but I wasn't really keeping track too closely, as one does when one's as pleasurably lost in a project as I was.
Total CostI don't usually go into detail in this particular category but this project was definitely more of an indulgence-motivated outing than a recycling or economical one. The total came to about £23 but, as those who know me will agree, I couldn't help myself. It's also a lot less than £202, which the original cost!
Get it in the necklace!
Tie each of your ribbons - at the centre - to the bases of your chains (the opposite ends to the clasps). Knot them twice.
Using pliers - or tweezers if your jump rings are especially small - link all your sections together via the extraneous jump ring loops.
