mother started a baby quilt some 45 yrs ago and now i want to finish it. it has 7 rows of 5 squares. the squares are sewed together but the squares are not of the same size. the smallest is 6 1/2 x 6 1/2. So the seams do not meet. i am a beginner quilter and have no idea how to finish this baby quilt. She has cross stitched baby animals on each white square and these are joined with a pink square. Do i need to separate all these squares and resize them? What do you suggest? Thank you donna
