Project introduction
This post is a pattern overview, not a full tutorial. The Mosaic Summer Seahorse is a confident-beginner-friendly mosaic crochet square by Crochet Hooks and Magic, designed by Elisa. It shows graceful seahorses ringed by coral, bubbles and a wreath of rolling waves, worked in mosaic overlay with a special popcorn stitch for texture. Find the complete free instructions through the Original designer’s pattern and instructions.
The square is worked in the round from the centre out using mosaic overlay, so you only handle one colour per round and never change colour mid round. Every round is worked from the right side with no turning, and the unused colour is simply dropped and picked up again when needed. Worked in the listed yarn and hook, each finished square measures 26 cm (10″) and can be joined into blankets, table runners or wall hangings.
The designer chose a bright ocean-inspired colour-change yarn against a white contrast so the motifs stand out, while solids also suit the design when you want the lines to stand out. For crocheters newer to mosaic, the square offers a chance to practise the popcorn stitch with standard stitches and charted repeats, while experienced mosaic makers get a fresh motif grounded in familiar technique.
- Contrast colour: James C Brett Baby 4 Ply in White (BY4), a 4 ply, 100% acrylic yarn with 439 m per 100 g.
- Main colour: James C Brett Shhh in Azure Delight (SH18), a DK weight yarn in 80% acrylic and 20% wool with 550 m per 100 g.
- Crochet hook: 3.0 mm (US D/3).
- Notions: stitch markers and a tape measure for checking tension.
- Tension: 24 sts x 24 rnds = 4 in x 4 in (10 cm x 10 cm), measured over back loop single crochet. Change hook size up or down to meet it.
- Terminology: US terms. Size: one size.
The designer shares the web version of the pattern free on her site, while an ad-free printable PDF is available for purchase through her Ravelry shop. That split is worth keeping straight: free web access does not make the PDF free, and the paid PDF does not mean the web version costs anything.
Crochet Pattern Abbreviations
The designer uses US crochet terms, and her abbreviation key covers the shorthand below. Standard definitions are kept in their exact technical form so you can match them to the charted rounds, while the special stitches get their own overview in the next section.
Colour and general shorthand come first. Use this group to track which yarn is in hand and how each round is described:
- CC stands for contrast colour.
- MC stands for main colour.
- ch stands for chain.
- rep stands for repeat.
- rnd stands for round.
- sc stands for single crochet.
- sl st stands for slip stitch.
- st stands for stitch.
- yo stands for yarn over.
Back loop shorthand covers the flat background stitches:
- blsc expands to back loop single crochet.
- bl-popcorn expands to back loop popcorn stitch.
Front loop shorthand covers stitches that drop down to draw the picture:
- fldc means front loop double crochet.
- Lfldc means left front loop double crochet.
- Rfldc means right front loop double crochet.
- Lfltr means left front loop treble.
- Rfltr means right front loop treble.
- Lfldc2tog means front loop double crochet 2 together to the left.
- Rfldc2tog means front loop double crochet 2 together to the right.
Special Stitches
The texture of this square comes from a family of special stitches worked into the front loops two rows below, a hallmark of mosaic overlay. Alongside plain back loop single crochet, the pattern leans on front loop double crochet and longer treble variations that lean left or right, plus paired decreases that pull two front loop double crochets together on one side.
A back loop popcorn stitch supplies the raised bubble texture scattered around the seahorses. It is formed from a small cluster of double crochets closed into one puff within a single stitch. If you want every yarn over spelled out with diagrams, the designer’s downloadable PDF carries full explanations for each special stitch.
- fldc drops two rows down into the front loop only of a stitch two rows down, and one stitch of the current round is skipped.
- blsc goes into the back loop only of the next stitch.
- Lfltr and Rfltr are the longer treble versions. Lfltr skips the next 2 stitches before placement, while Rfltr is placed two stitches to the right. Each skips one stitch of the current round.
- Lfldc and Rfldc are the double crochet versions. Lfldc is placed in the next stitch to the left, while Rfldc is placed in a stitch to the right. Each skips one stitch of the current round.
- Lfldc2tog and Rfldc2tog join two front loop double crochets. Lfldc2tog works into next stitches two rows down, while Rfldc2tog starts one stitch to the right. Each skips one stitch of the current round.
- bl-popcorn uses 4 bldc in the next stitch, then the dropped loop is picked up and pulled through the first double crochet to close the puff.
Written Crochet Pattern…
The square begins with a magic circle and grows outward, alternating main colour and contrast colour. Each round introduces its own colour on the last yarn over, so you only ever work with one strand at a time. Early rounds establish the centre and corners, with stitch counts rising steadily as the square takes shape.
Mosaic overlay does the heavy lifting for the picture. Plain back loop single crochet rounds in the contrast colour alternate with main colour rounds where front loop double crochets drop two rows down to draw the seahorses, coral and bubbles. Left and right leaning trebles and double crochets tilt the lines, while two-together decreases shape tighter curves, all worked from the right side without turning.
Raised popcorn bubbles appear in the middle rounds, giving the underwater scene its playful dimension. The pattern notes keep the mechanics tidy: slip stitches go into the back loop only, the first stitch of each round sits in the same stitch as the previous round’s slip stitch, and chains plus modified corner stitches stay outside the stitch counts. All back loop single crochets go into the top of the stitch from the previous round as normal.
All front loop double crochets go into the front loop of the stitch immediately below, two rows down, and the matching stitch of the current round is skipped.
Two designer tips flag shared placements. In round 10, two stitches share one stitch. In the round after round 13, the first stitch of a 3 fldc group shares the front loop of the previous Lfldc stitch.
The closing rounds, rounds 25 through 30, set up the rolling wave border that frames the whole motif. The designer flags this section for a careful stitch and count check before moving on, since accuracy here keeps the waves even. A plain closing round smooths the edge, and then you fasten off and weave in the ends.
This square belongs to the designer’s mosaic collection, which also includes Celtic Clover, Floral Spring and Tulip Trance, so it mixes well with her other motifs. Because this article is an overview rather than a tutorial, treat it as your project guide and shopping list, then work the complete round-by-round text from the designer page linked in the introduction.
The pattern is by Crochet Hooks and Magic, signed by Elisa. She asks that the pattern be shared by linking to it rather than reprinting, and that it not be sold or distributed, though you may keep a copy for personal use. Finished pieces may be sold with clear credit to Crochet Hooks and Magic, but mass production or factory manufacturing is not permitted. The designer invites makers to share finished makes with #crochethooksandmagic.
