Quilt Patterns: Star Blocks for Beginners

The short answer

Start with a Friendship Star made from square units. It teaches triangle trimming while keeping the block assembly in straight rows.

Start a star quilt with a simple Friendship Star made from squares and half-square triangles, or HSTs. Sew the units in straight rows before trying diamond stars. The plan below makes a 12-inch finished block; twelve blocks make a 36-by-48-inch quilt top.

Cutting supplies for a first star quilt: a ruler and mat, or a set that includes both

1. A long ruler for cutting squares and straight strips.
2. A cutting mat with a printed grid.
3. Or a three-piece set with a rotary cutter, ruler and mat together.

Match supplies to your project

Star points need units that meet at the same outer size. Start with a measuring ruler and cutting surface you can read clearly. If you have no cutting tools yet, compare the set with buying a ruler and mat separately. Choose a ruler with marks you can read at the starting and trimming sizes.

Our quilting guide covers fabric and finishing choices. Make one star block before deciding on a whole quilt. That sample shows whether you enjoy trimming the triangle units as well as joining the rows.

1. OLFA ruler for starting squares

OLFA QR-6x24 six-by-24-inch frosted acrylic ruler

Our verdict:

Star cutting measurements

Best for cutting long strips with a rotary cutter.

Keep in mind: hold the ruler securely and keep your hand clear of the cutting edge.

The OLFA QR-6x24 is a six-by-24-inch frosted acrylic ruler. Its long edge suits straight strips and larger rectangles. Check the markings against your fabric and keep the whole cut over a suitable cutting mat.

2. OLFA mat for manageable units

OLFA RM-SG 18-by-24-inch cutting mat

Our verdict:

Star-unit work surface

Best for rotary cutting on a medium-size work surface.

Keep in mind: store flat and keep it away from heat; a rotary mat is not an ironing surface.

The OLFA RM-SG is an 18-by-24-inch double-sided self-healing rotary mat. Mark those four corners on your desk with removable tape to check the fit. Leave room beside the mat for fabric and the closed cutter.

3. OLFA cutting set for a new workspace

OLFA RTY-2C/STQR quilting and sewing kit

Our verdict:

Starter star cutting kit

Best for starting rotary cutting with a coordinated cutter, mat and ruler.

Keep in mind: check the included mat and ruler dimensions against your work space before buying.

The OLFA quilting and sewing kit groups a rotary cutter, cutting mat and acrylic ruler. It is useful when the whole cutting station is missing. Check each item's current dimensions against your desk and pattern before ordering.

Star quilt pattern: choose triangles or diamonds

A Friendship Star uses four two-color triangle squares around a plain center. Its units join in three rows. A traditional Lone Star has diamond sections with angled joins. Follow the cutting and sewing steps for the type of star you want to make.

Use our Lone Star guide when that large diamond star is your goal. The AQS lesson hosted by BERNINA shows how to make HSTs two at a time, starting with squares large enough to trim afterward. Use that method for the four triangle units in the block below.

Cut one 12-inch Friendship Star

Every grid unit finishes at 4 inches and measures 4 1/2 inches before joining. For one block, cut one star-color center square and four background corner squares at 4 1/2 inches. For the four HSTs, cut two 5-inch star-color squares and two 5-inch background squares.

Pair each 5-inch star square with a 5-inch background square, right sides together. Mark one diagonal. Sew 1/4 inch to each side of that line, then cut on the line. Open the pair and trim each HST to 4 1/2 inches, keeping the ruler's diagonal guide on the seam.

Arrange a three-by-three grid. Put background squares at the four corners and the star square in the center. The HSTs fill the four side positions. Use the diagram to keep their colored halves rotating in one direction around the center.

In the top HST, put star color at lower right. Place it in the right HST at lower left. For the bottom HST, place it at upper left. The left HST needs it at upper right. Check all four positions against the diagram before sewing the rows.

Join the star and build a 36-by-48-inch top

Join the three units in each row. Each row should measure 12 1/2 by 4 1/2 inches. Join the rows, matching their vertical seams. The unfinished block should measure 12 1/2 inches square. Inspect it before cutting a larger batch.

If a row is too short, measure its three units separately. Each should still be 4 1/2 inches wide. If those sizes are correct, inspect the two seams for excess width. A row that is too long needs the same checks. Fix the row before joining it to the others, so the block stays square without stretching.

Twelve blocks in three columns and four rows make a 36-by-48-inch finished top. The full cutting count is 48 background corner squares and 12 star center squares at 4 1/2 inches. For the 48 HSTs, use 24 star squares and 24 background squares at 5 inches.

Check the multiplication: each paired set makes two HSTs, so 24 pairs make 48. Lay out all twelve stars before joining. You can adjust star colors by block while keeping the background constant. For planning smaller fabric cuts, read quilt patterns using fat quarters.

Keep points from disappearing at the joins

Leave the full seam allowance around each trimmed star unit. Check the size before joining rows, then sew with an even allowance and match the seam intersections. A seam sewn too far from the edge can cut off a point even when the unit began at the correct size.

If a point is wrong, check its HST rotation first. Then check trimming and seam width. Our half-square triangle guide gives more practice layouts. Compare beginner quilting machines if controlling a slow, steady seam is part of your equipment decision.

Verdict

Start with one measured Friendship Star to practice trimming HSTs and joining a nine-unit grid. Check that the sample is 12 1/2 inches square and that all four colored triangles rotate around the center as shown. Then cut the pieces for the twelve-block top.
