3) A square dowel the length of your garden bed;
4) Lots of nails (depends on how many plants you have and how many nails you need to place dowel)
6) 20 inches of picture hanging wire (or other bendy wire--you can use something from jewelry making too, or you could use string too).
1) Cut your twice so that it's about twice the length from where you are going to place your dowel to the base of your garden beds. Cut as many pieces as you have plants to train. I had ten blue lake beans so I cut ten pieces of twine.
Do the same for the other end so that they are about equal looking:
Here's Ralph helping.
He LOVES that straw.
He's been hunting something in that corner.
This is what it looks like when it's hung on the nails.
