How does cotton sheets get heavier than their raw material?

[strawman]

So as you weave cotton sheets from the cottonballs, you slowly become more and more encumbered. Physics smackdown?

Weaving bonus on slottables? Fewer cotton consumed per sheet, over 500 balls of cotton, quite an effect if your bonus is even +175


[Edit]

Started with 1000 clean cotton weighing in at 116.78 KGs including gear and tools, with a meager weaving bonus of +175.

Finished with 7 clean cotton left over, 133 cotton cloths, 150.41 KGs with same gear and tools.

I'm sure this will get nerfed now that I say it, but the nearly bottomless inventory, tea, and present bonus to the weaving system makes it very easy to profit from growing cotton. So I say on behalf of cotton-hermits everywhere: Thanks, JC!

Oh wow you're right, that's an unexpected side effect of that bonus! I feel much better now

Sheets still weigh more than raw cotton with 0 weaving bonus.

If the values are off on the 0 bonus case, you should report the weight of the puffs and of the cloth in the Bugs section so it can be adjusted.

It is the answer to Mass Defect.
Each time matter converts to energy or energy to mass, a small portion of the total ceases to exist. There are countless theories as to why, including it being evidence of multiple dimensions as that mass/energy must go Somewhere.

Now we have the answer. It traverses space and time to become a portion of the mass of refined cotton in Salem.

I believe Woven Reeds are heavier than individual reeds.
