thanks for the compliment, norah, but please don't ask me. i'd never do that block the way marcia does. criminitly!!! that's a lot of extra, unnecessary cutting and piecing!
that block should be divided into four. 25 of the little white squares should be consolidated into one big square. i'm halfway through a sextuple irish chain using a similar method. (blocks have been done since november; just started assembling the top this morning.)
no matter how you do it, though, it's an excellent candidate for strip piecing.
but don't toss that third pin yet, steve. with or without SP, you must, must, MUST pay VERY close attention when you're setting up the strips. then proceed methodically as you assemble the subcut strips into blocks. SP saves a lot of time in creating the rows. However, because of all the different colors, it's very easy to get a row in the wrong place as you build the block. SP makes it easier still to lose track of which row gets pressed which way.
go in peace, and good luck, grasshopper. :P
