Details and Where To Buy the Best Cornhole Bags Resin Pellets
Since I have been running www.ResinBags.com, I have been getting a lot of questions from visitors about PERFECT BAG specifications for those that want to make their own. This post will give you all that you need to know.
1) The resin that you use needs to weight between 6.2 and 6.8 oz. per cup. So, as you know, a cup holds 8 oz. of water. The weight of the resin in that measuring cup needs to weigh less than water, but not below 6.2 oz once the measuring cup is full. Why? Well, when you go to fill your bag with a lighter resin, persay 5 oz. per cup, you bag will need more resin and in turn it will be TOO PLUMP. If you use too heavy of a resin then your bag will be too thin and droopy (though I know a few players that like really thin bags, in this case a heavier resin is ok). Most sellers of resin will tell you that the resin they have weights x amount of ounces per cup. Just do the math, if they haven't already, and make sure it is between 6.2 and 6.8 oz. per cup (BE SURE TO TARE THE CUP SO AS NOT TO INCLUDE ITS WEIGHT), with 6.5 oz. per cup being PERFECT. -------------- 0.7 ounces or so will be made up by the material, so 2 1/3 to 2 1/2 cups of resin + the material will put you in that 15 to 16 ounce range. As long as the bags is between 14 and 16 ounces when sewn you are within specification. NOTE: Don't buy sharp edge or cylindrical resin. It will make your bag feel crunchy, which sucks. You want to try for rounded edge resin for a nice feeling bag.
Here are a few vendor links (click on blue links below) that sell within this recommended weight range:
(A) For this resin supply option (A) YOU WILL NEED TO MIX A HEAVIER AND LIGHTER WEIGHT BATCH TO GET IN THE RIGHT RANGE. HERE IS HOW: What you need to do is take 1) this white, rounded 5oz/cup resin listed RIGHT HEREand mix it with 2) an admin tested heavier off-white, rounded 8oz/cup resin listed RIGHT HERE to get you within the optimal range listed above weight wise.
(B) Here is a GREAT new offering for resin pellets with NO MIXING REQUIRED!. The respective seller in the industry states it is the perfect weight, plus it is rounded (which is a big plus for not crunchy bags). Buy it RIGHT HERE.
(C) Here is another GREAT new offering for resin pellets with NO MIXING REQUIRED!. The seller states 6.3 oz per cup which is perfect. Buy it RIGHT HERE.
(D) I am happy to report that my friend Zac has created a new product for all-weather cornhole bags called SynCorn. SynCorn™ is the ultimate synthetic cornhole bag fill. Cornhole bags filled with SynCorn™ can achieve proper weight (6.5 oz. per cup), feel and thickness within regulation guidelines. The manufacturing process provides a consistent and ideal size to weight ratio similar to corn. NO MIXING REQUIRED!. Buy it RIGHT HERE.

I will update these links as I find recommended resins. If not listed here, then I probably won't recommend it.
COST: 2014 resin rates should run you between $2.25 and $2.75 per lb. shipped when you buy up to 8 lbs. The savings comes in when you buy 16 to 50 lbs. Then you can get it for around $1.85 to $2.25 per lb. shipped.
2) If you use 6.0 oz/cup resin, then you will use 2 1/2 cup of the resin to fill your 100% duck cloth bag.
3) Your duck cloth should be cut 7 1/2" x 15" before sewing. Your duck cloth along with thread will weigh between 0.7 and 0.8 oz. Fold it in half and you will sew the 1/2" zone all the way around, leaving a small opening on the 4th side for the resin fill to go into after you flip it inside out. Here is a link about sewing the best bags. Anything that I say here in this post about resin fill specifications trumps anything that is in that posting. There might be minor variations, but wanted to state that.
4) Once your bag is filled and closed and patted flat, it will measure 1 1/4" to 1 1/2", with 1 3/8" being nominal. If your bag is over 1 1/2" thick, then it is too plump and you either used a too small piece of duck cloth, you sewed outside of the 1/2" zone perimeter or you used a resin fill that is less than 6.0 oz/cup and put too much resin in it to get it up to the right weight (14-16 ounces).
That's it. These are the specifics you will need to make the PERFECT bag size and weight.
