Stack-n-Whack vs. OBO
 

:confused: What's the difference between a stack-n-whack and a one block wonder? They look like the same block to me....is it the same block, but called by two different names? TIA, Beckie

I dont know but would like to find out also. joyce j

I was thinking the same thing. I guess the stack-n-whack are done with pre-cuts and the OBW is a way of fussy cutting certain parts of a repeat pattern on yardage, but I am not completely sure.

I did a stack-n-whack and it wasn't made with pre-cuts. I had to find the repeat in my fabrics and cut the exact same piece to make my block. It was a butterfly and I had to turn every other piece over and match it up so it looked like there was movement in the butterflies wings.

The colors are really much more vibrant. It was a wallhanging gift for my MIL and she had it framed and the picture was taken with a camera phone.

i think that stack and whack is pieced with other fabric to make the block square and the one block wonder connects the octagons? without pieces in between. i've never made one of either of these, but have the fabric sitting in my 'to do' pile :)

Okay, I found this link that discusses Stack - n-whack http://www.bethanyreynolds.com/what'ssnw.html

and this link here on the board for OBW http://www.quiltingboard.com/main-f1...bw-t86303.html

The basic technique of stacking exact repeats of fabric and cutting to make a kaleidscope looking block are the same.
Stack-n-Whack was the first to develop the method. Others came later. OBW usually has no sashing between the sections. The first Stack-n-Whack design was the Kaleidscope Pinwheel. Other desgins came later - fans etc.
Both methods gave a new way to cut and piece kaleidscope designs. Prior to this, they were fussy cut using templates.
Stack-n-Whack is also a registered Trademark name by Bethany Reynolds.
Both methods rely on cutting exact repeats from the fabric. It is important to follow the directions exactly as while it might appear that the motif is repeated throughout the fabric, the only exact is down the fabric otherwise the registration of the motifs can be a little off and the finished product a bit off.

Thanks Holice. I do sew appreciate the help / info :thumbup:

Thanks for the clarification. I thought they were the exact same thing.

And to add to your vocabulary ..
4PP = 4 Patch Posey!

This one is only four layers/repeats for squares.
OBW requires six repeats ... thus hexagons.
SAW/SNW ... often are 8 repeats ... octagons.

All are the same general concept as Holice mentioned ... and just spins from the other!
