I loved making this pattern in the Elann worsted superwash...
It is for my friend whose daughter is FINALLY coming home from the hospital, Cora suffers from :: Trisomy 18::..
I made the 6-12 mos. size and it took about as long as a HAT! ((joy!!))
For this size I used almost ALL of the solid and had more left of the multi- I have not weighed the skeins yet.
As far as pattern/MODS... and using 2 colors...
Obviously I used one color for the top.
I used that one color through the pick-up of sts for the body.
I worked the 4 edge sts in the original colors, adding the new color for the central portion. I did this by going from both end s of the single skein of the rose color. at the end, I changed back to using just pink on the last page, where you start the garter ridges after you work you total stitches for a set number of inches... for more info--
