This is a recipe for something very similar to best press. Mark Lipinski's starch recipe:
Boil 1 qt water
Dissolve 4 Tab liquid starch in 2 cups cold water (this makes a light starch--use more for a heavy starch).
Add this to boiling water and return to boil.
Then add 2 more cups of cold water--place in spray bottle (I put the extra in plastic milk jugs). Store in cool
place. I love this mix. I use light starch and add a bit of lavender water.
