i would suggest using fishing wire to sew the sequins with because it is much sturdier than cotton thread.posted over 2 years ago
you can buy sequins that are already strung on thread, like a spool full of it. it would be considered trim i think, in that section of a fabric store. but im not sure how that would turn out overall on your cardigan.
i would suggest getting some of that and laying it out all together to see how it looks, and then maybe sew or glue it on ….?
I think it would be easiest to buy sequin covered fabric. It’s definitely more difficult to use the sewing machine with sequin fabric but it is possible. You just have to be careful and do it slowly. (I’ve had to hem a sequin jacket before with a sewing machine and it took awhile!)
but I think it would take far too long to sew the sequins on one at a time if you want the whole thing to be covered! You could always try gluing the sequins on instead but i’m not sure what it would look like or how long it would last!
