So I'm knitting a scarf for Alex that involves stripes in three colors. I messed up the order the other night and freaked out but apparently there is a way to fix it, called "frogging."
So I Googled it and came up with this, but while the photos were pretty it didn't really help since the pattern is a 1 x 1 rib. Instead I found some videos on this site, which helped tons. Basically you thread your needle on the row you want to start up again and then just rip all the rows out. I practiced on scrap yarn first until I got it.
Just goes to show you, even when there's no one around to help, the Internet is always there for you. It's how I learned to knit in the first place. 2 scarves down, 2 to go. Eeesh!
