Thought I'd share a "Duh - dope slap" moment with you in hopes it helps someone not have the same experience. . .
So there I was . . . printing off a Steve Good pattern using Inkscape to make the cutting lines red.
The pattern: "Baseball Teams" consists of 4 pieces - a base with slots and three other pieces with tabs to fit into the base plate.
I discovered that if I turned the Printer's "Borderless" setting to "on" the pattern on the printed page is stretched 1/4".
I learned this after cutting out one of the pieces with tabs and found the tabs would not line up with the corresponding base slots.
It baffled me for a time until I realized the page of the base plate was printed using the printers "Borderless" setting set to off - and the other pieces were printed on a different page with the Borderless setting set to "on".
It had me going for awhile, but after some experimenting I got the "Aha" (translation: You dummy!).
