I bought a pattern leaflet today for several baby afghans.
Two of the afghans call for casting on with a US13 needle and k1,p1 for several rows before changing to a US15 needle to begin the body of the blanket. The first and last ten stitches on each edge of the blanket is still working k1,p1 though.
In the pictures on the leaflet and a couple others I found online it's obvious that the stitches worked on US13 size are pulling in narrower than the body of the blanket.
Is there a good reason to follow the pattern on this or should I just stick with the US15 for the entire blanket?
The only reason I could think the designer changed size was to keep the edges looking neater, but with the rib stitch I wouldn't think that would be such a problem.
I'm pretty new at blankets so any help / advice is appreciated.
Thanks in advance,
