Hello! I have an making a bag. I'm using what I believe is a simple shell stitch. Its spaced and has 3DC in each space. Anyway it's a large bag and I'm starting from the bottom but as I go farther up I would like the width of the bag to get smaller. Is there a way I can decrease the stitch without it looking horrible obvious? I don't know how I upload a picture. Sorry.

Thank you very much.
