Sea Glass Sanctuary Crochet Wall Art Crochet Pattern

Transform crochet into statement-making fiber art with the Sea Glass Sanctuary Crochet Wall Art Pattern, a large circular lace design created to bring texture, beauty, and a sense of calm to your space.

Worked outward in the round, this oversized crochet motif becomes more than a traditional doily or mandala when it is stretched and mounted inside a large hoop. The open lace, repeating geometry, and radiating stitches create dramatic shadows and dimension while allowing the wall behind it to become part of the design.

I created Sea Glass Sanctuary for my own studio, where I wanted something handmade and substantial enough to anchor the space while still feeling light, coastal, and peaceful. I love the idea that the things we make can do more than decorate our homes—they can help turn an ordinary corner into a place that feels distinctly ours.

Although mine became large-scale wall art, the crochet motif itself offers plenty of room for interpretation. Change the yarn weight, hook size, color, or finished presentation to make the design your own. It could easily be a mandala, a circular lace shawl, a blanket or throw, a bag, the crown of a hat, a tablecloth or even a rug.

Fasten off.

Finishing:

Weave in loose ends. Hand wash. Block to finished measurements and allow to dry.

Assembly:

Determine the Size of the PEX Frame

After washing and blocking the crochet motif, allow it to dry completely and measure its finished diameter.

Because the PEX tubing is 1/2 in (1.3 cm) thick, add 1 in (2.5 cm) to the diameter of the crochet motif to determine the outside diameter of the frame. This accounts for 1/2 in (1.3 cm) of tubing on each side of the circle.

For the 48 in (121.9 cm) diameter Sea Glass Sanctuary motif:

48 in + 1 in = 49 in frame diameter

Next, calculate the circumference of the frame by multiplying the frame diameter by π (3.1416):

49 × 3.1416 = 153.94 in

Round to approximately 154 in (391 cm) of PEX tubing.

For a different size motif, use the same formula:

Blocked motif diameter + 1 in = frame diameter

Frame diameter × 3.1416 = length of PEX tubing to cut

Measure and mark the PEX tubing before cutting. For the cleanest and easiest cut, use a PEX or tubing cutter. A fine-tooth saw can also be used; secure the tubing before cutting and smooth any rough edges afterward.

Tip: Before cutting, remember that the coupling joins the two ends of the tubing and may slightly affect the final circumference. If necessary, test-fit the tubing and coupling and make small adjustments before permanently assembling the frame.

Assemble the PEX Frame

Insert one end of the PEX tubing firmly onto one side of the 1/2 in coupling. Bend the tubing gradually into a circle, then insert the opposite end onto the other side of the coupling.

Push both ends securely onto the coupling until the connection is snug and the circle is closed.

Lay the frame on a flat surface and gently adjust it until the circle is as even and symmetrical as possible.

Attach the Crochet Motif to the Frame

Cut a long length of matching yarn and thread it onto a yarn needle.

Position the blocked crochet motif inside the PEX circle, centering it as evenly as possible. It can be helpful to temporarily secure the motif to the frame at several evenly spaced points around the circle before beginning the final wrapping.

Beginning at one ch-2 space along the outer edge of the motif, pass the yarn through the ch-2 space and wrap it securely around the PEX tubing.

Continue wrapping the yarn around the PEX tubing only 9 times between each ch-2 space. At the next ch-2 space, pass the yarn through the space and around the tubing to secure the motif to the frame.

Repeat this process around the entire circumference:

Attach through ch-2 space, wrap PEX tubing 9 times, attach through next ch-2 space.

Keep the tension firm and consistent as you work. The motif should stretch evenly toward the frame without distorting the circular shape.

The additional wraps between attachment points serve two purposes: they secure the crochet motif to the frame and gradually cover the visible PEX tubing with yarn, creating a more cohesive finished appearance.

Continue around the entire frame, adjusting the motif as necessary to maintain even tension and spacing.

When you return to the beginning, secure the yarn firmly and weave in the remaining end.

Gently adjust the motif and frame one final time so the crochet is centered, evenly tensioned, and the frame maintains a smooth circular shape.
