Ocean Paradise Crochet Throw Blanket Pattern: Trinity Stitch

Last updated on June 5th, 2026 at 01:33 pm

The Ocean Paradise Crochet Throw Blanket combines rich texture, beautiful ocean-inspired color, and simple repeating stitches to create a cozy blanket you’ll be proud to display in your home. The Trinity Stitch creates gentle ridges that resemble waves rolling across the water, while the ribbed border adds a polished, professional finish.

One of my favorite things about this blanket is that once you complete the first few rows, the pattern settles into an easy repeat. The stitch pattern may look intricate at first glance, but it quickly becomes relaxing and rhythmic. Whether you’re making this blanket for your own home or as a thoughtful handmade gift, the repetitive design makes it an enjoyable project from start to finish.

Yarn Substitutions and Stash-Busting Ideas

This blanket was designed using Caron Simply Soft yarn, which creates a soft, lightweight throw with beautiful drape and excellent stitch definition. The Trinity Stitch texture really shines with this yarn’s smooth finish.

If you’d like to shop your stash before purchasing new yarn, many other #4 medium-weight yarns can work well in this pattern. Keep in mind that some worsted-weight yarns are slightly thicker than Caron Simply Soft, which may result in a blanket that is a bit larger or denser than the original.

Great stash-friendly alternatives include:

  • Red Heart Soft
  • Premier Everyday Worsted
  • Lion Brand Basic Stitch Anti-Pilling
  • Hobby Lobby I Love This Yarn
  • Big Twist Value
  • Caron One Pound
  • Caron Jumbo

For a blanket with even more texture definition, choose a smooth yarn rather than a fuzzy or heavily textured yarn. Solid colors, gentle ombrés, and self-striping yarns all work beautifully with the Trinity Stitch pattern.

If you are not able to find the yarn locally, you can purchase it online. Savings Center – Pattern Princess

Using leftover yarn from your stash? This pattern is a great candidate for color changes. Try alternating colors every few rows, creating wide stripes, or working sections in coordinating shades inspired by the ocean theme.

As always, make a small gauge swatch before beginning. Different yarn brands can vary slightly in thickness, and a quick swatch can help you determine whether you need to adjust your hook size to achieve the desired finished measurements.

Crochet Pattern Notes

Pattern is written in US Terms.

This pattern is a repeat of row 2 until you reach your desired size.

Try and keep your stitches a bit loose. This will help you be able to get your hook into the stitches in the previous row.

Turn at the end of each row.

Crochet Border consists of alternating the front post double crochet and back post double crochet stitches. With three double crochet stitches worked in each corner.

Crochet Stitches

Chain Stitch (CH)

Begin the chain stitch by making a slip knot on the crochet hook. Leave about a 5-inch tail on the yarn. This will be woven in later.

Next snug up the yarn loop that is on the crochet hook; while it should be firm, it should also be loose enough to slide on the hook with ease.

Keeping the loop on the hook, wrap the yarn over the crochet hook from back to front. Draw the yarn through the loop. You’ve just made a chain stitch. Yarn over again and draw the yarn through the loop on the hook. Continue yarning over and drawing the yarn through the loop on the hook to make more chain stitches.

Double Crochet Round 1 Border

Crochet Border Directions for Ocean Paradise Crochet Throw Blanket

Round 1

Pull up a loop in any stitch to the left side of a corner stitch. Chain 3 (Counts as a DC). DC in each stitch around. (On the ends work a DC in each ST, work 1 DC for each row for the sides. In the corners work 3 DC in the corner ST). End the round with a SL ST into the top CH of the first CH 3.

Round 2

CH 2 (Counts as a DC). (The stitches on this row are a bit shorter than the regular DC, therefore, I used a chain of 2 for matching height). Complete an alternating ST pattern between FPDC and BPDC.  Corners: When you get to the corners, continue to work 3 DC into the middle DC ST from the previous row. However, on the other two stitches from the previous row DCs in the corner – blend those into the alternating FPDC and BPDC stitch pattern. End the round with a SL ST into the top CH of the first CH 2.

Alternating Front Post and Back Post Double Crochet

Rounds 3 and 4

Repeat round 2. However, make sure to complete the FPDC and BPDC where the previous row FPDC and BPDC have been completed. This elongates that stitch and creates the beautiful, ribbed look.

Finishing

Work a chain stitch, cut the yarn off leaving about a 12-inch tail. Draw the yarn through the chain stitch and pull snug. Use the yarn needle to weave in the yarn tail and snip off excess yarn.

Review on This Crochet Blanket from Etsy Customer, “I have been crocheting for over 60+ years. I have made hundreds of afghans and have hundreds of afghan patterns. This is the best pattern I have ever crocheted. The instructions were very detailed and expertly written. The Trinity Star stitch is beautiful and I loved the border. Well done.”
