Now or Later

Last night at knit night a couple of us were working on shawls with numerous ends.  The discussion turned to weaving in ends.  Do you weave them in as you go, or do you weave all of them in at the end.  

If you have just a few ends, it's not an issue.  But when you have two dozen or more, it makes you think about the most efficient way to deal with all of them.  I debated this problem last summer when I was working on my Purpleplexy.  In the end I decided to follow the pattern's polite suggestion to weave in the ends as you go.  

I hadn't given it much thought when I was working on my current project, but after last night's discussion, maybe I should.

I'm halfway through my Ysabel, and there will be twice as many ends to contend with when I'm finished.  I'm going to take out my tapestry needle now.

How about you.  Do you weave in ends as you go or save them all for later?
