after i've prewashed my fabrics i like to saturate them with a starch solution.
canned starch isn't strong enough.
also, when you use as much as i do the cost really adds up.
a hand-pump sprayer can seem like a lot of work after a while.
my hands get tired. (apparently, they are as lazy as the rest of me.

)
the pump triggers wear out, too.
and then it hit me ....
holds more.
more durable.
easier on the hands and wrists.
really soaks the fabric with minimum effort.
and they don't cost much.
