Doh!

After I had weighed my Linus scraps on my cheap kitchen scales, I realised the bathroom scales would be much more accurate. 

If you turn your head, you'll see the bathroom scales weig the same drawer at 5.5lb.  I'll take that as a baseline.  

So, after a fair amount of sewing in the last week, here is the result. 

 Fifty 6.5" MAM blocks, and the scale says 

Hooray!  At least it's going down.  I have neglected my Allietare, but will catch up later.  Here's to the scraps!
