Best solution would be to keep your minimum Fractional as variants.
We have achieved similar things with multiple stores.
@ashukasma this is awesome! My only question is with inventory management. Does it not get confusing tracking your inventory with so many variations? For example when you add a new product you have to add all the quantities in the boxes manually?
If I have 1 metre of fabric I would add:
0.1 x qty 10
0.2 x qty 9
0.3 x qty 8
And so on...leading to lots of manual work. Is this correct?
@LandonGartner yes, its going to lot of manual work, but this is the only solution in shopify, I think people is quite friendly with this solution.
