Yet in quilting it makes a HUGE difference!
This photo shows TWO one inch square reference blocks -
I would have said that they are both the same size, yet the square on the left is just ever so slightly out.
I didn't realise anything was wrong, I measured the block drawing, it was only a little bit out so I concluded it "was not to scale"...
I made up my first block and fussed over the fact it did not sit right. No matter what I did it would not go together!
I blamed everything from my own lack of talent to the 'dodgy' 1/4" seam of my machine -
I re-measured the reference block, I checked my computer - it was set to print at 100% - so what was wrong?
What I didn't know was, when we unplugged the Printer for a day recently it reset the custom settings to "Fit to Page" when it was turned back on.
Apparently it didn't matter what my laptop was programmed to do - the printer ALSO had to be set to 100%.
On each piece it is only a 'bees whisker' on the side seams - But the REAL issue was that One Sixteenth of an Inch at the bottom of the fan shaped piece on the right hand side.
Mystery solved and now my pieced 6 1/2 inch blocks are going together like a dream!
