Thank you so much everyone, I am going with the 3" As a beginner, I would rather trim than mess them all up. LOL
I had a great day today, I cut strips with my new rotary cutter and mat It went really slow for me because I was so nervous, I just pray I have them all straight. LOL I cut out 600 little 2.5" squares and tomorrow I have another 600 to cut out and then another 600 of the 3" size, then I am excited to say, I am ready to start sewing them all together. I can't wait to see my first block I love this board, everyone is so helpful and knowledgeable. Thank you all so much Rachel
