01 / Choose your material

What’s on your project list?

Start with the space you need to fill—or work backwards from the bags you have.

02 / A practical process

From the first measurement
to the final shopping list.

Keep the numbers that matter in view. Each tool separates the space you’re filling from the allowances you choose.

Inside the calculations
  1. Measure the space

    Use a rectangle or circle, with the depth you plan to add.

  2. Check the material

    Enter your supplier’s bag size, price and any justified allowances.

  3. Build your list

    Save each area or layer, then print one useful record of the order.

03 / Before you order

A little knowledge goes a long way.
