If you draw the block yourself, as opposed to using one already in the library, sometimes EQ is clever enough to figure out the piecing order. And sometimes not.
When you select Foundation Pattern from the Print options, you'll notice 3 different tabs:
Numbering
Sections
Options
If you go to the Sections tab, you can Start Over and YOU decide how you want to group the pieces. You just click on separate units and then GROUP. If you click in the order you'll sew them, then the numbers will be assigned that way.
There are some wobbles in the process - you can't correct a mistake - you have to start over. And you have to finish the block before you click on one of the other tabs. If you do that and come back to the Sections tab, you can add to what you've done and have to start over again. Slightly annoying but you'll get the hang of it.
After you've made the groups you want, if you want to change the numbering sequence within a group, then click on the Numbers tab. Within a group, click the sequence you really wanted and the numbers will change accordingly.
The options tab is pretty self explanatory. And you'll have to play around a bit with those so you're comfortable with the options. What I might select might not be what you'd want.
You can always click Preview to see how it will print without wasting paper.
The foundation pattern printing is one of my most favorite features in EQ.
