Stop it right now! Okay got that out of my system. Yes more practice is the answer. If you are giving these to charity or non quilty people don't worry. All giftees are so overwhelmed by the process, they think its all amazing.
Agree with others who say don't SID, first of all, you are only sewing over stitches??!!: two try a zig-zag or wavy stitch. As it goes over the seam allowances, you are really holding the fabrics together.
Had a wonderful teacher who NEVER allowed us to put ourselves down. We were told okay that technique is one we will not do anymore, let's try this. Poof better everything. Have a nice cup o' tea and just get on with it. Love in stitches to all.
