I've been looking for patterns to make for Spring that only use 1 x 50g ball of yarn in an effort to introduce some of the more 'boutique' yarns to my local girls... I love using nice yarn but when you're paying anywhere from $9.50+ per ball those projects that take more than 1/2 a dozen do seem a tad on the expensive side...
What do you think??? What kind of yarn do you like to purchase and is there a limit that you put on yourself when it comes to the price???
This dress was a great little '1 ball project' that I whipped up in only 2 evenings
(free pattern available here). 
I used some Debbie Bliss Ecobaby yarn which sells for $9.50 a ball. I would so totally use this yarn again!!!! It was silky smooth to the touch and a dream to knit with... The colour, almost teal, is divine and looks just gorgeous teamed up with the blue/black wool/linen blend that I used for the skirt of the dress...
I'm really loving cotton at the moment and have used it again to make this little pair of super cute baby booties for my
shop.......

It's Sierra and is another gorgeous yarn!!! The 80% cotton, 20% wool blend is just exquisite!!! It has a real texture to it that allows it to mould beautifully to a pattern....
There are so many gorgeous yarns available which really makes me excited to be a knitter/crocheter.... What's a great yarn that you've used lately, one that's really made your heart sing???
