Step 1: Cut Your Jelly Roll Strips

From each 2½-inch jelly roll strip, cut:

Keep the rectangles and squares from each strip paired together. Each strip gives you enough pieces for one and a half blocks, so you'll sort matching fabrics into groups of four for each complete Card Trick block.

Step 2: Build the Center Four-Patch

Select four 2½-inch squares from four different fabrics — these will form the center of your Card Trick block.

Arrange them in a pleasing layout. Sew them together in pairs first (right sides together, ¼" seam), then join the pairs to create a four-patch. Nest your center seams — press one seam left and one right so they lock together perfectly.

Step 3: Add the Card "Fans"

This is where the card trick illusion takes shape. Take two of your 4½-inch rectangles (from two of the same fabrics in your four-patch center) and position them extending outward from the center.

Before sewing, add a 2½-inch background (white) square to each end of the rectangle sections. You'll need four background squares per block — these create the negative space that makes the cards appear to overlap.

Sew the background squares to the ends of the rectangles, press, then attach the rectangle-and-square units to opposite sides of the center four-patch.

Step 4: Complete the Block

Add the remaining two rectangle sections (with their background squares) to the top and bottom of the block. When you press everything open, you should see the four "cards" fanning out from the center, each one a different fabric, with white corners creating the illusion of depth.

Your finished Card Trick block should measure approximately 6½ inches square (unfinished). Make as many blocks as you need for your quilt size — Jenny uses the full jelly roll for a generous throw.

Step 5: Create the Setting Squares

Jenny sets her Card Trick blocks on point (rotated 45 degrees), which gives the quilt a dramatic diamond layout. To do this, you'll need 7-inch background squares to alternate with your blocks.

Cut your background fabric into 7-inch squares. Then take your remaining 2½-inch colored squares and snowball two diagonal corners of each setting square:

Step 6: Cut Setting Triangles

After snowballing, cut each setting square diagonally from corner to corner. You'll get two setting triangles from each square. You need four setting triangles per Card Trick block — one for each side — to create the on-point framing.

Attach the setting triangles to all four sides of each Card Trick block. The snowballed corners will create a subtle color accent that echoes the card trick pattern.

Step 7: Assemble the Quilt Top

Lay out your framed Card Trick blocks in diagonal rows. Sew the blocks together in rows, then join the rows. Add corner and side setting triangles as needed to fill in the edges and create straight quilt boundaries.

Finish with a 5-inch outer border using your border fabric. The border frames the entire on-point design beautifully, giving the eye a place to rest after all those gorgeous overlapping cards.

💡 Pro Tips

Keep fabrics organized: Label or stack your cut pieces by strip so you don't mix up which rectangles go with which squares. This keeps the card trick illusion intact.

Accurate ¼" seams matter: Because the block has multiple intersections, consistent seam allowances ensure all your points match up beautifully.

Snowball shortcut: Instead of drawing diagonal lines on every setting square, just fold the small square in half diagonally and press a crease. Sew along the crease — no marking needed!

Choose high contrast: The card trick illusion works best when your prints are distinctly different from each other and from your background fabric.
