I bought 3 skeins of HSpun for my NEBB too and thought i'd perhaps have tons left over because it seems like it knits up so quickly. However, i had a teensy problem with mine..
I did mine on 10.5 needles instead of the recommended 11 because that way i didn't have to buy new needles. I kept increasing until i had approximately 140 stitches on the needle (instead of the recommended 126) because i wanted it to be a little bigger and i was using slightly smaller needles. Those extra rows took up quite a bit of yarn, but i still think i would have been ok with 3 skeins.
However, as i was finishing out my third skein, I hit a patch within the yarn that was defective. Not a knot, but a very large section in which it seemed like some of the ply was missing. It was really thin and faint in color. I had to remove it (about 1/4 of the skein!) and buy a 4th skein to finish. (that had me slightly irritated but i figure i'll send back the defective stuff and let them know).
Anyway, i finished with LOADS left over in the 4th skein so i've made 2 hats and will probably make a baby sweater (see: LionBrand's "Bend it like Baby" pattern on LionBrand's website
without the stripes. The hats are really cute and knit up easily except i don't think Hspun is good for pompoms even thought pattern calls for one.. When it unwinds it gets kinda.... icky.)...
If i had a digital camera i'd take pictures but i don't! :( Sorry!
Dunno if that helps but that was my experience
