So here are the steps to this tutorial:
Step #1: Cut the stems of the roses in water to shorten them so they absorb the liquid faster
Step #2: Slice the stem into 2, 3, or 4 parts so you can place them in separate colours
Step #3: Pour warm water into clear glasses (cold water works too but it will be slower)
Step #4: Mix in 2 tsps of sugar & 2 tsps of white vinegar (to help colour retention)
Step #5: Mix in the food colouring (the brand I'm using here is RedMan)
Step #6: Place the stalks in the colours you want to be absorbed into the rose/flower
Step #7: Leave them in a cool area to sit for 24hrs minimum.
