I started with some flax seed I got at the local health food store, very inexpensive.
Then I made my bag, very simple.... piece of scrap cloth, folded in two, sewn up the sides then made two more rows to create channels, leaving the top open. I used a funnel to fill the tubes with the flax seed that I had scented with lavender, then sewed the opening shut.
I found an old pair of PJ's that the elastic had failed in and used that to make a cover so it would look cute.
Very easy and quick!
Have a cup of tes and sit back with your new heating pad. :) Happy comfort time. ~nan
