Charts are generally pattern only, though sometimes charms and beads maybe included. You need to then order fabric and threads. If you want us to organise this for you and contact you with a price then add this information to the comments box.
Where a size is shown in stitches that means you choose the size fabric you like working on best or that will give you the dimensions you need. To work out the size, divide the stitch count by the fabric count and that will give you the size in inches. Multiply by 2.5 to get centimetres.
