Two Completely Different Sizes

Slippers is what I'm talking about.  I knew if I made them on different machines this could happen, but that they'd be so different surprised me.  I made one at the SMKG with my bulky Toyota KS650.  The other I made at home with my bulky Studio MOD. 155.  What a difference!

Now I know when I made the one on the Toyota I didn't change the tension for the outer slipper.  My question to myself is what tension did I use for that slipper?  OK opened up my traveling machine (Toyota) and the tension I used for the inner and outer slipper was 9.

The pattern has three different tensions mentioned, 8, 9, and 10.

The slipper I did at home last night was tension 9 for the inner and 10 for the outer.  So, I'll have to do some unraveling of a slipper in order to get 2 that are the same size.  I'm anxious to try and felt a pair and see what I get.

The slipper on the left is the one I knitted on my Studio MOD. 155 T9 for the inner and T10 for the outer.  The slipper on the right was knitted on my Toyota KS650 T9 for inner and outer.
