Ashlee Brotzell Releases March Butterfly Interlocking Mosaic Crochet Square Pattern

Designer Ashlee Brotzell published March Butterfly, the third large square in her 2026: A Year of Butterflies series, on her blog with the post header "by ashleebrotzell | Feb 28, 2026 | 40-Window." March Butterfly recreates a monarch butterfly on a coneflower and is offered as two separate pattern files, one for interlocking crochet, the other for overlay mosaic crochet.

Brotzell's site copy describes the files plainly: "You will receive two files: The Locked Filet Mesh (LFM) interlocking crochet method..." and the overlay mosaic file. The pattern is a large square motif that "shows a Monarch on a coneflower and is our 3rd large square in the '2026: A Year of Butterflies' series of interlocking and mosaic crochet patterns," language carried in the blog post header and pattern listing excerpts.

Technique details are explicit in the pattern notes. For interlocking, the Locked Filet Mesh method "uses only chain spaces and double crochets to create a mesh; two colors are worked alternately which creates the pattern." For mosaic, the instructions state "Mosaic crochet uses single crochet and double crochet stitches. The double crochet stitches cover some of the other color’s single crochet stitches to create the design." The mosaic version is described as "solid because it uses a chart that was adjusted from the interlocking version."

Left-handed crocheters are accommodated: the blog and listing specify, "This design comes with the fully written pattern (in both techniques) for left-handed crocheters so they don’t need to read every line backwards to get the letter legible." Charts are included as well, the post adds, "You’ll also receive charts!" The pattern uses US crochet terminology, and the technique notes reference YouTube tutorials for further learning, though the supplied excerpts do not include direct tutorial links.

Testing and sample credits are detailed by name. The pattern was "Tested by Henriette Van Wyck, Nancy McKain, On A Poad Trip, Sonjia Schultz, & Teresa." The Ravelry excerpt ties specific samples to testers, listing "Mosaic crochet sample by Teresa," "Interlocking crochet sample by Sonjia Schultz," "Mosaic crochet sample by On A Poad Trip," "Interlocking crochet sample by Nancy McKain," and "Mosaic crochet sample by Henriette Van Wyck." Ravelry-page metrics shown in the excerpt include "12681 projects" and "stashed 5630 times," though the supplied text does not clarify which listing those numbers describe.
