Go to a fabric store and buy 1 yard of polyester viole fabric. It will be 108" wide. Cut it like you want it and take the pieces to an alteration shop. I paid $5 for the fabric and $12 for the sewing and wound up with 2 bags strong enough for 20-30 lbs of grain.
I used the paint strainer bags and large coarse wine making bags from the LHBS. The fabric is finer mesh and stronger.

Yep...ahem...I know him well
. $19 will put a nice well made bag in your mailbox in 3 to 4 days, link belowElDuderino

For those who are interested in a strong, well built bag sewn to the dimensions of their own kettle, please have a look at my web site:
bagbrewer.com
I have made bags for kettles of all sizes, from small stove top pots to a bag I sewed yesterday to fit the 55 gallon boilermaker.
I know a lot of guys like to make their own equipment, myself included, but this is another option for those who can't/don't want to sew...

another great place to get a bag is CustomBIAB. Been loving mine! check my sig for the review on my brewing blog

I too purchased a bag from custombiab and I was blown away. Great craftsmanship, very sturdy bag.

I have a 10 gallon pot and a recipe that calls for a 10.5Lb grain bill. I can do the no sparge method with this pot? If I figure 1.25Qts. per pound that rounds to about 2 1/2 gallons. My boil off is 1.25 gallons per hour so I add that to the 2 1/2 and get 3.75gallons. Then I add in the absorbtion of .63 gallons (using .06 for grain absorbtion rate) which puts me at 4.25 gallons. If I want 5.5 gallons post boil I need to have about 7 gallons in the pot and the grain which fits in my pot?
To sparge you can either drain or dunk using the amount of water needed to get to your preboil volume as long as the water is 170 degrees. Are the initial water ratios used above ok for using the sparge method or do you use more that the 1.25qt ratio?
BIAB really interests me and I am trying to get a clear grasp on the concept.
OK... first of all... forget 1.25qt per pound. With BIAB you'll be MUCH higher.
use this to determine the water needed. absorption+batch size+boil off+trub loss = water needed. to determine the absorption use grain in lbs x .065 = absorption.
so, based on what you listed above, you have a boil off of 1.5 gallon per hour. You want 5.5 gallons. if you assumed a trub loss of .5 gallons you'd need
.68 +5.5 + 1.5 + .5 = 8.18 gallons. Which you can reduce to 8 gallons and still easily hit the numbers you're looking for. That was all based off of 10.5 lbs of grain as you listed above. it will EASILY fit in the 10 gallon kettle. I have done over 15lbs with no problem. it just comes right to the top of the kettle
for me since I squeeze the heck out of the bag and my trub loss is only .25 gallons in the kettle my volume needed is a bit less.OK... first of all... forget 1.25qt per pound. With BIAB you'll be MUCH higher.

Thanks this is the info I was looking for. I kept getting confused the more I read on it. I like BIAB is less time consuming and plan to try it in a couple weeks for my next batch.
Ive been using this http://beerreviewdude.com/biab-calculator/comment-page-1/#comment-51282 to figure out how much water I need.
Ive done 6 batches of BAIB, they all taste great I just wish I could get a little better efficiency... I like bang for my buck, but my last batch had 70% but thats because I ran 1.5 gal sparge water through my bottling bucket with the bag sitting in a turkey fryer strainer bucket thing.

I do the same thing with the turkey fryer strainer. As soon as I am done with the mash I just put the bag of grains on the strainer over a bucket until my wort comes to a boil and dump whatever I collected back into the boil kettle. I've been getting 70-75% efficiency using this BIAB method. As long as it is 70% or above I am happy. I'd rather pay a little bit extra and hit my numbers consistently than be 85% one batch and only 70% the next.
crush the hell out of those grains.. I mean really crush them. then run them through one more time just for good measure. you'll get better efficiency. I get 75% or better each time. Oh yeah... squeeeeeeeeeeze that bag.

I do it after a fashion in the BrauMeister. It has a grain pipe and water is circulated through the grain during the mash. One thing I noticed no one mentioning was to take a large spoon during the draining and stab the grain several times to break it up a bit. This helps it drain better and if you decide to sparge to make up for lost volume, the water drains through more easily.
