New Blocks Needed Calculator — enter your block's finished size and instantly see how many blocks (and what grid of columns and rows) you need to piece a crib, twin, full, queen, or king quilt.
Floss Color Conversion Tool now includes Anchor — alongside DMC and Cosmo, find the closest match across all three brands by color, not just DMC↔Cosmo.
Favorite your calculations — star your go-to results on the History page so they're always at the top (Maker & Master Quilter).
Shopping list improvements — sort your list by date, name, or category; add amount and category right from a quilt's project card; share buttons now sit below your list instead of above it.
New: Conversion Tools — just want the Thread, Fabric, and Floss conversion tools without the rest of Maker? Unlock them on their own (included free with Maker or Master Quilter).
Plus smaller fixes and polish throughout.
