Usually a sport weight ?
hmm…okay how close is that to DK then? they are about the same right?
ooop no the yarn weight thingy says that it is lighter…hrmmm
so sport weight is good for baby blankets right or should i add a third?
It’s not an exact science. A lot depends on the yarn itself. I think your best bet is to do a swatch with two and three and see what it looks like. I’d generally say two fingering is close to dk. I don’t even think other countries have yarn they call sport weight.
Okay, wait, I know this one. Is it “one in the hand” or “two in the bush”?
No, it’s six of one, half-dozen of another. 
For a baby blanket … use what ever will make it go fastest… they are often neverending!
lol i agree with you but i have a plan to battle that! just trying to figure out how close to DK weight i will get with fingering weight yarn!
and then that Ingrid person keeps talkin’ about the swatch word…i swear she hates me when she talks to me like that! hmph
hehe :rofling:
I didn’t catch that it was for a baby blanket! No swatching necessary!
Forgive me? :shifty:
lol always! 
In my house, the following theorem has been proven:
Two strands of fingering weight = (tangled mess)*(much swearing and flinging of knitting equipment)
So I just don’t go there anymore. :oops:
