1.Trace the block onto the interlining as shown in the drawing. Here we have used a spacing of 3 cm between the lines. Start with a square in the middle (1) then trace the rest of the fields as shown in the drawing. Cut the centre square (1) measuring 4.5 x 4.5 cm out (finished square of 3 x 3 cm). Cut strips measuring 4.5 cm wide (finished width 3 cm) from the fabrics you wish to use for the block. 
2.The entire block is sewn on the right side along the traced lines. Use a stitch length corresponding to 5 stitches per cm and 0.7 cm per seam. Start by placing the centre square (1) on the interfacing and pinning it in place. 
3.Now place the strip for field 2 on top of the square with right sides facing and pin in place. 
4.Sew the strip, starting and stopping approx. 0.7 cm outside the line. Unfold the strip, cut off the excess and press it in place. 
5.Now place the strip for field 3 on top of fields 1 and 2 with right sides facing and pin in place. Sew the strip along the traced lines. Start and stop 0.7 cm outside the line. 
6.Unfold the strip, cut off the excess and press it in place. 
7.Continue in this way until you have finished sewing the entire block. You always work in a single direction: clockwise when looking at the block from the right side. Once the block is finished, cut so that the outermost strip is 3.7 cm wide and you are left with a square measuring 22.5 cm. You can also sew the fabric and the interfacing together at the outer edge using a 0.4 cm seam. 8.You can also sew a Log Cabin block without using interfacing. To do so, simply sew the pieces together, cut the strips and press it all together in the order shown. Using the same type of fabric for all pieces will make the process easier if you are not using interfacing. Make sure that your block keeps its shape along the way. It may be easiest to cut it as you go. A traditional log cabin block is assembled with two connecting sides in a light colour and two connecting sides in a dark colour. The centre square is often a reddish colour, symbolising the cabin fireplace. The light and dark sides of the square symbolise the bright and dark sides of the cabin respectively.
