Introduction: The Collegiate Foam Sack
A couple of year ago, I produced a very large sack that was not only comfortable, but people loved it. There was only one problem with this sack, It was a bit too big. With college coming quick I needed something that would still have the same qualities only a bit smaller. We have to remember college dorms aren't the biggest things in the world. The basic shape is a 4' by 3.5' cylinder with 60lbs of foam. This sack was modeled off of the classic Movie Sac. The benefits of making your own sack is saving money and making it exactly how you want it! This sack seats about 2 and is perfect for you and your special someone.
Step 1: Sack Prep
- 60lbs shredded poly foam (2 bags of 30lbs)
- 22 Feet of durable fabric
- 22 Feet of fuzzy fabric (faux fur)
- 4' zipper
- 4 feet of Velcro
- Sewing machine
- denim needles
- lots of thread!
Overall cost: 150-200$
Step 2: Cylinder Shape
The basic shape of the sack is a cylinder that is 4' by 3.5'. The longer you make the cylinder the less fluffy it gets. Make one, 4' 4'' circles in the fabric. The extra 4 inches is for the sewing. The next circle you make you will need to make a little wider on one end to compensate for the zipper and the Velcro. If you fold the fabric in half and cut a circle you can make sure the circle is even.
Step 3: Sew All Sides Together
When sewing everything together you must remember to sew it outside-in. When you flip it to right side-in all the seams will be on the inside and the outside will look professional. I started off by sewing both circles to the 13' rectangle. Then i came and sewed the final line to connect it all. Make sure you take your time on this part and double stitch everything. This will prolong the life of your sack. once everything is done flip it around and pour the foam in!
Step 4: Cover
Now for the cover. When making the cover do everything the same, except do not put Velcro on. The zipper will have to be bigger since it needs to fit over the foam bag. I used a 6' zipper and wrapped it around the sack a little as shown in the picture.
tips-When picking a fabric for the cover try to get a little stretchier fabric, if not make the cover a littler bigger to compensate for the movement of the sack.
Happy Sack Making!
Here's a video me and my friend made a three years ago with the bigger sack!
