Has anyone ever had real luck with dying their washed out black clothes black again? I have tried that Dylon stuff on a few occasions and have been very unimpressed, the dye will last one wash, if it even takes. I've only ever dyed Jersey items like tracksuits and Tshirts. Works better on jeans perhaps?
I use "Persil Black" on dark clothing which works great.
I tend to buy super-cheap casual clothes from The Warehouse (NZ store) - cotton tops and singlets are only $7 (very cheap for here), and they do the most incredible range of CoolDry leggings for $17, or standard black leggings for $12. Everything washes up great but because I typically wear them to death, little holes do appear in various spots.
Pre-lockdown, I would have just thrown those items out, but the hassles with getting stuff delivered during that period as well as stock levels being highly impacted (they still are; most of this stuff either comes from India or China), made me want to repair them and once I realised how easy it was to do (mostly with little iron-on patches which I bought 100 of in varying colours for $5 from a market), I decided to keep doing it.
I'm quite handy with a sewing machine and know how to sew buttons, etc., but I used to only bother repairing my good, and work, clothes ... besides, it was hard to sew up holes on my casual clothes as it would make most of the clothes look a bit weird (pulled-in).
One pair of leggings had a few holes around the knee area (I suspect from our washing machine), which I ironed a little gingham patch into last week; they actually look kind of cool now.
