How much fabric do you need for your DIY dress?

We recommend fabrics with widths between 140 and 150 cm for the fabric requirements table below. When dealing with fabrics of different widths and designs (striped, plaid, etc.) the pattern placement may need to be redone.

Check your contraction!

The first step in preparing your fabric for cutting is to wash it. Thus, you will preshrink the fabric and remove any excess coloring. The garment will therefore remain true to size once it is sewed and won't shrink after the first wash
