yard update

My yard has been covered in thick plastic for about a month.  A lot of the weeds underneath are very brown.  But some were green! 
To kill the green ones,
I mixed up a non toxic "Round UP' alternative and sprayed it last weekend.
I boiled down a gallon of regular vinegar that is 5% acidic.  Boiled down to 16 oz or 1/4 the amount, so I think that should have quadrupled the acidity to make 20% acidity.  That's considered "herbicidal strength".  I added a dash of liquid dish soap and a T of rubbing alcohol.  Used my pressure sprayer. Will let you know!  I hope this kills the weeds, root and all.  Regular vinegar kills the tops of weeds, but if big weeds, they come back...

frugality with buying paper towels, and toilet paper

How do you compare the myriad of choices for paper products to find the best bargain?
How do I know  if a coupon makes it cheaper or not?

I began  my notebook writing down  the total square meters per package and price. Then I'll figure out price per square meter.  It gets a bit tricky due to varying quality of the products, but that will come.
Will let you all know, dear readers, what I discover!

It took about an hour at Sam's Club, then another hour at Walmart writing down the stats on all their products for paper towels and toilet papers.  (I can't believe how many different types of packages Charmin makes!)

It is tedious work so I have to take breaks!
