I just picked up a sheet of 1/2" HDPE sheet 20"x70". I only need about 64" for my front deck/table. So that gives me 2 at 20"x3" to try out... good Idea!

This is what I was thinking of using to do exactly what MT4runner said after looking at everyone's replys.

Where do you get sheets of HDPE or the" rigid porous bottom" like in the pic of the groover stower before?

Good idea on the plastic corner pieces. I prolly have a trash can I can cut up for that. (side note: it's ridiculous the stuff I build outta plastic trash cans...y'all should see the fishfinder and 2 pole mount I made outta one to fit my ducky!)

I think I'll sew some loops into one end of some straps-thread them through a rigid bottom of some sort and use the slides on the other side. If I put it together like this I can just put my tarp in the bottom with the edges up to effectively make a basket and keep things (like the small cooer) from slipping through the cracks in the strapping.

One poster I saw mentioned a "chicken flooring material" that looks like that rigid porous bottom in the pic I posted. He was using it as a side decking material and it looked decently strong.

You're getting this third hand. Beware.

A 2' x 4' piece is under $24 at amazon:

Here is another source, more expensive but looks the same.

Note the pictures and other uses.

So you want to make your own dropbag huh? Here is how I made mine. 1) Materials: You need the following:
Sewing Machine
Upholstery Thread
Tape Measure
Cam Buckles (try
1" Webbing for Cam Buckles
1 1/2" Webbing
Fabirc - I used textline which I got from Petersen Canvas in Fort Collins. Everything I used was scrap so it was free! But it was also only 15 inches wide, so I had to sew a few pieces together to get the right size. Rockywoods fabric also sells this.

2) Sizing and Layout

I was making a drop bag for a captains box/cooler and a small ammo can, so I need one to fit in my 25" rower's compartment with the bottom of the bag 12" wide, but you can size them anyway you want. Here is what you need to layout.

So in my case i need the length (right to left) to be (9+24+9+1 = 43") and the width (top to bottom) to be (9+12+9+1 = 31"). This will result in a bag just shorter than my rowers compartment that is 9" deep. It results in the cooler sitting about 12" below the top of the frame.

The reason I added the 1/2 borders is so that the edges can be hemmed. Once you get the shape cut out, hem two opposite edges at 1/2" hem. It is best to hem the sides that will have the cam buckles first. You now have an inside and an outside, the inside is the side you folded the fabric towards.

Next, you need to lay out the straps that support the drop bag. In this case, I only had two, running lengthwise (right to left above). I like to have my tails 18". This gives enough length that I can lower the drop bag, or string it to a far rail, or around anything in the way. So, in this case, I needed straps that were (18+42+1 = 78" The reason the I used 42 instead of 43 is because I lost an inch when I hemmed the fabric. It should looks something like this:

Pin the straps to the fabric approximately 1 inch from the corners. You will loose 1/2 an inch when we sew the corners, so this will result in webbing approximately 1/2 an inch from the corners. (Note, if you are making a 4 strap dropbag, I would space the webbing 11 1/2" inside to inside). Make sure you pin the straps to the outside of the dropbag!

Now that you have the straps laid out, time to start sewing. I spaced my stitches 1-2 mm and used heavy duty upholstery thread. Just sew two straight lines down each side of the strap.

(A few notes on sewing. Use pins to hold the fabric together before you start sewing, its much easier. Invest in a good denim needle. You'll need one for this type of work. When you first start, be sure and run forward an inch, then back to the start so that your end doesn't come loose later. On my machine, I can hold a button in and the machine will go backwards. A ripper [to pull out stitches] is really helpful because no matter how hard you try, you will inadvertently sew one side of the bag to the other. Speaking of which, be sure the rest of the fabric doesn't get folded under while you're sewing, or you'll be using the ripper!)

Sew a box on the strap. If your machine will let you offset the needle to each side, this will help you stay close to the edge.

Alright, you've got all your straps sewed on. Next we need to do the corners. Mark a line 1/2 inch in all the way around the "T". Next, cut diagonally at each corner to your mark. Now, fold each edge, starting at the corner together so that the two inside edges are facing out. Pin it. What you are going to do is sew this, and then turn it rightside out later so that it looks good. It should look something like this:

Once you have finished all 4 corners it should look like this:

You'll notice three things if you look close. First I pined the strap tails so I wouldn't inadvertently sew them to something, second the corner has one side taller than the other. This is because we haven't hemmed it yet. Lastly, the bag is inside-out.

Next hem the un-hemmed edges so that they are the same height as the other piece. Be sure and fold the fabric the right way.

Now you're ready to do the rest of the corners. You'll need 4 6" pieces of 1 1/2 " webbing. Turn the bag rightside out, and pin the webbing so it overlaps each corner joint, and is even with the top of the bag.

Like this:

Sew it on. You'll notice I boxed this and put an x in it. Its helpful to use both forward and backwards on the machine, and put the machine near the edge of the table so that the rest of the fabric has a place to hang while you sew. Let the machine do the work, all you need to do is guide it.

Now that the 6" strips are done, you need to add the top horizontal strip of 1-1/2 webbing. You can see above that I started near a corner, and worked my way around over the blue straps, and the corner straps. I also used a wide zigzag stitch to lap the ends together. (Don't sew the blue strap tails on accident. I did one this time around and had to undo it.) If your machine can't get through the areas with multiple layers of webbing, just come back and sew those by hand.

Almost done. Now we need to do the buckles. You'll need 4 4" pieces of 1" webbing. You are after something like this.

You want the bottom of the webbing to be 5" from the top, or so the cam buckle, when pulled tight will be just below the 1-1/2 webbing. Its helpful to first pin the webbing to hold it together, and then pin it to the dropbag. Again, sew an X. If this is too much for your machine, you may need to sew it by hand.

Once all the buckles are on, you just need to cut your blue strap tails at an angle and melt them so they feed through the buckles easily.

It took me about 4-5 hours, but I'm a little slow.


I got the fabric for free from Peterson Canvas in Fort Collins, but i would guess textiline is aroudn 10 dollars a yard, and you shouldn't need much more than 2 yards TextileneŽ PetTex PVC Coated Polyester Mesh - Black

Cam and straps I got from Best place I could find. I went a bit overboard and bought 50 buckles and 1000' of each webbing. I would suggest just getting the regular weight, not heavy duty unless you have a nicer sewing machine.

Overall, I bet I spent 30-40 dollars?
