To change the size, you simply have to make a larger or smaller copy. Use Vlieseline (brand of fusible webbing) as foundation and sew on the pieces of fabric according to the Log Cabin technique.
This block consists of several patterns. Copy this page to the desired size and draw the lines onto the Vlieseline. Draw the groups containing a letter somewhat further from each other than shown on the model. Cut out all the patterns on the paper. Use the mirror image of these patterns on the backing. Cut out the pieces of fabric including a seam fold.
First sew together all the parts per group according to their numerical order. Then sew the groups together in the indicated order. This block has been designed by Heleen Pinkster for Wilma Karels Embroidering and Quilting.
