There are some items that are perpetually on that mental list and are automatic purchases when they show up for the right price. Scrabble letters fit this category because they are so handy for a variety of projects that include gift wrapping and table settings.
At the Goodwill Outlet store the other day where everything is sold by the pound, I saw four of these. (2 tall and 2 short) They were so tangled together that at first I wasn't even sure how many there were. I spent some time getting them separated and then some more time wondering how I would use them. Finally I decided I now had too much time invested in them to leave them behind. (This should not be a tough decision at 39 cents a pound but my storage area is getting a bit crowded and sometimes I have to talk myself into things no matter how cheap they are.)
Yesterday I stepped over this iris stem that was growing parallel to the ground and thought...I should stake that up with something.
And lo and behold, I had just that something.
So now that beautiful-to-be iris is upright and ready to blossom with out being trampled.
And random shopping has been vindicated once again.
