From Travellers Yarn Blog:
If you have knitted a sweater, tried it on, and it is too short, there is a relatively easy way to fix it. Of course, if the sweater is knitted top down, you can just rip it back to the ribbing and continue down. If however, you have knitted bottom up (which is the most common style of sweater construction), all is not lost.
Here’s the fix! http://travellersyarn.wordpress.com/2009/04/08/fixing-knitting-that-is-too-short/
Fall will be here before we know it, and that means there are holidays coming right behind where we might be entertaining at home. It’s always fun to have a hand knit touch in your home for other people to see, and if you’re going to be in the kitchen all day you might as well have some nice knit dish cloths to use.
