Stitch in the ditch is the easiest way to quilt for a beginner - not even!! But it you have that sewing foot with the flange in the middle - that is the way to go. Wish I had one years ago - I do,now!
Log cabin blocks are a literal piece of cake if ---- you measure and cut each log to exact length press each seam as you sew (this is for all blocks) and if you do a really good 1/4" seam. Seam allowance is VERY IMPORTANT - no ifs, ands or buts. That's more than just my humble opinion.
