Altering the Everyday skirt with the Building Block Dress book

Hello! I have made the Everyday skirt twice and I love it. Inspired by the Building Block Dress book, I would like to try a few alterations. Has anyone tried the following or have any advice, please: 1. Deeper waistband- I like a wide waistband. Would the skirt still work with an extra half inch or extra inch added to the waistband? Am assuming I would need to add length to the back panel and the waistband piece, right? Has anyone tried this? 2. Hem facing- following the instructions on p128 of the book, has anyone tried a hem facing? I would like a contrasting hem. Would I draft it from half of the front panel, one side panel and half of the back? 3. Patch pockets- I love the pockets but I fancied large simple patch pockets as in p94 from the book instead. Has anyone tried this? Thank you! Liz
