I tried the strip method and realized that my garment sewing experience was interfering. I then tried cutting the strips to size and always putting the strip about to be sewn on the top. If there has been any stretching while pressing on the previous rounds, your feed dogs will help compensate. I much prefer using strips cut to a specific size and found that my blocks rarely needed any trimming.
I have a friend who also prefers the strips cut to size but swears by only finger pressing the seams until the block is complete. She has wonderful colour sense and makes amazing blocks. I have been honoured to put them together for her (charity and community quilt tops take a lot of time to complete. Many hands make light(er) work sometimes)
