Although most people assume that reversible quilts comprise two surfaces constructed separately and joined together afterwoards, this isn't the case.
Although the number of blocks depends on the quilt size, they are constructed individually and only joined together when all
Before constructing the first block one prepares all
the fabrics which will be used. Log Cabin blocks are constructed by
starting in the center and building outwards to the edges. As one
starts, one must also prepare one piece of batting which is the same
size as the two center pieces. For both A and B sides the surface
side of the fabrics must face outwards, with the batting in between
creating a "sandwich".
From there one attaches fabric and batting
alternately. When attaching fabrics to the initial "sandwich" the
surface sides must now face inwards. Sewing both new pieces to the
"sandwiching" one then folds the new pieces outwards, and it is
usually best to use an iron to create smooth surfaces on both sides.
Then one inserts a piece of batting (without seam allowance).
Keep repeating this alternating process until the block has reached
the desired size.
In this manner one creates as many blocks as needed. When joining them together one additional strip is placed between each pair of blocks.
