Even though its nearly winter... in the UK, I still wanted to share with you a DIY I did with various shorts using bleach.
Instead of dip dying the bottoms, we dip dyed one side.
2 plastic containers (one for bleach another for water)
Dip the shorts into the bleach
Leave in for 3 minutes
Wash out in the water and leave to dry. Place a garbage liner underneath, so the bleach doesn't stain the floors.
Unfortunately I do not have a photo of those specific shorts.
However, here is a different version, where we splattered bleach onto shorts. Its the same way, just instead of dipping the bleach, get a paintbrush and splash your shorts all over.(Place shorts on bin bags). Again, wash after 3 minutes and leave to dry
