How many charm packs do I need to make a quilt?
The table below lists the number of squares needed for suggested finished quilt sizes. I also calculated the number of charm packs needed, assuming your packs contain the typical 42 pre-cut squares. If your charm packs have a different number of pieces, you may have to adjust these calculations accordingly. Also, if you prefer any extra length or width to your quilts, then just add an extra row of squares. Easy peasy.

| Baby Quilt | 31″ x 40″ | 63 (7×9) | 2 |
| Crib Quilt | 36″ x 54″ | 96 (8×12) | 3 |
| Lap Quilt | 54″ x 67″ | 180 (12×15) | 5 |
| Twin Quilt | 72″ x 99″ | 352 (16×22) | 9 |

What is a charm pack?
A charm pack is a pre-cut pack of fabric squares. Precut charm squares typically come with a pinked edge and are astandard 5-inch, but due to the 1/4″ seam allowance,finished squares will measure 4.5″ x 4.5″.
Most packs come with42 squaresfrom a single fabric collection, so they are a variety of fabrics that all coordinate and complement each other. This makes charm packs perfect for making cohesive patchwork quilts with a variety of beautiful fabrics. This also makes precut charm squares a great option if you are seeking a fast and easy quilt.
Where can I buy charm packs?
For beginner quilters, making a quilt for the first time, I suggest buying a couple of charm packs from your local quilt shop. If want to add any additional fabrics to your charm pack, like some coordinating solids, you can simply cut 5-inch squares from yardage. You can cut 56 5-inch squares from 1 yard of fabric.
If you can’t find any charm packs at your local quilt shop, Fat Quarter Shop is an online shop that has a massive collection of charm packs. Moda Fabrics is one of the fabric companies they stock and they are known for their gorgeous charm packs.
