Many Trips Progress

I've made some progress on my Many Trips Around the World quilt but I can see where this one will be somewhat slow going.  First, the pieces are 2" squares.  Secondly, it has to be laid out on my design wall before sewing together.  This is what I have so far:

 

upper left quadrant

 

across the top, not at all straight

 

 

I was running out of room on my design wall so decided to sew the upper left quadrant together and then lay out the rest of the design.  

I am sewing the pieces together in blocks of 5 by 5.  I thought of doing 10 by 10, but was afraid of what an unsewing job it would be if a piece got out of place.  5 by 5 is more easily controlled.

Here's a finished block back on the design wall.  There is considerable "shrinkage" after sewing.  What started as a 10" square becomes 8" when sewn (will be 7.5" finished). 

The design wall is a relatively new addition to my sewing space and I can't imagine making this quilt without one!
