A friend is expecting twin granddaughters at the end of the year, and has ordered both cot quilts and a floor quilt. She's been very easy to please and had no particular requirements for the design or colour.
I found a lovely easy cot quilt pattern through Etsy called Leafy Treetops by meags & me. I made two with the same material but I quilted different designs on each.
Plenty of ruler work on the squares and lots of free motion on the elephant blocks.
