How to make Plant Markers from recycled materials

After years of slicing up plastic yogurt containers to make weatherproof markers
for my plants, I realized I could get a lot of raw material from just one mini-blind.

A standard Mini blind will yield 160 plant markers!

Step 1: Assemble Your Supplies

Find a used venetian blind.  
I went to Freecycle and asked for broken venetian blinds had several
offers in an hour. 

Next find a pair of kitchen shears, a wash basin, a sponge, a towel,
some dish soap and a few magic markers.
