Anyone have any suggestions on how to model burlap sacks?  Full ones that is.

Since I'll be needing quite a few I'm looking for something simple, quick, and cheap.

I work in 1/35 scale if it makes any difference.

Hi Michael,

I would be happy to 3D print you some.

Hi Michael,

Seeing you are working in 1/35, have a look at Italieri (60 bags)

Tamiya sandbags (48 bags)

Miniart 35586 hessian bags

Buy one of those 3 to get the size of a bag.

However if you are after several hundred individual bags,
then you could use air-drying clay and your own mould
(using the commercial stuff as a size guide to stamp 'em out in quantity).

For this type of stuff your mould needn't be too fancy.
Just 2 pieces of close grained wood with a 1/2 bag size cavity in each.
Two trackpins or small nails should be sufficient to ensure alignment as the halves come together.

If you line the cavity with a teabag settled in with a thin smear of white glue,
then you might be able to stamp a fabric texture into each bag when it is moulded.

Provided that the bag comes out of the mould cavity OK,
you should be able to make a bag in under a minute.

Something like talc or baby powder rubbed into the mould cavity and separation plane,
might help the clay release from the mould.

If you slightly overfill the cavity,
then this will give you a side seam that can be trimmed after the clay hardens up.

With a bit of practice you'll be able to estimate pretty accurately,
how much clay you need for each bag in the mould.

Also remember any "not-so-successful" bags,
can be buried in amongst a pile of good bags,

Good luck, and let us know how you go.

I recently saw where someone made several from modeling clay,

and they were able to make them 'draped' over one another accordingly,

as they look in real life.

I intend on making a stack doing exactly the same thing.

I think you're right, a mold would be the way to go. 
Especially since I would want several dozen sacks.

Just need a couple of master sacks to make molds of. 

I've tried making a few out of an old tee-shirt to get the texture,
but not pleased with the results. 

Working on carving a few sacks right now, to see how they turn out.

Unfortunately I'm on a very strict budget (zero) for the time being,
due to unforeseen expenses.
