Blocking Optional But Helpful

• Lay each square flat
• Pin corners to sharpen the square shape
• Lightly steam or wet block depending on yarn type
• Let dry completely before assembling

Marking The Openings

Lay The Squares

• Place the two granny squares on top of each other with edges lined up
• Decide which side will be the inside of your top

Mark The Neck Opening

• Find the top edge center
• Mark the center section for the neck opening
• A simple guide is leaving the middle open and keeping 3 clusters on each side of the neck
• Adjust wider or narrower depending on your preferred neckline

Mark The Armholes

• From the top corners down along the side edges, count about 6 to 7 rows and mark that point
• Everything above the marker stays open for the armhole
• Everything below the marker gets joined

Try On Fit Test

• Carefully pin or hold the sides and shoulders where you plan to join
• Put it on over a top
• Check that your head fits through the neck opening comfortably
• Check that the armholes feel roomy and not tight
• Adjust your stitch markers if needed

Joining The Crop Top Vest

Prepare For Seaming

• Turn the squares inside out so the seam will be on the inside
• Line up the corners and edges so clusters match as neatly as possible

Join The Side Seams

• Join yarn at the bottom corner
• Single crochet through both layers along the side edge
• Work one single crochet per stitch or evenly through the spaces to keep it neat
• Stop when you reach the armhole marker
• Fasten off or keep yarn attached if you want to continue the shoulder seam

Join The Shoulder Seams

• Join yarn at one top corner edge
• Single crochet across the top edge toward the neck marker
• Stop at the neck marker to leave the neck opening open
• Fasten off
• Repeat on the other side of the neck opening if needed so both shoulders are joined evenly

Turn Right Side Out

• Turn the vest right side out
• Check that seams look neat and the fit feels correct

Optional Bottom Hem Border

Round 1 Hem

• Join yarn anywhere along the bottom opening
• Chain 1
• Work hdc evenly around the bottom edge
• Place hdc in each stitch and also in spaces as needed so the hem lies flat
• Slip stitch to the first hdc to join

Round 2 Hem

• Chain 1
• Work hdc in each stitch around
• Slip stitch to join
• Fasten off and weave in ends

Optional Finishing Touches

Clean Neckline Or Armhole Edge

• Join yarn at the neckline edge
• Chain 1
• Work single crochet evenly around the opening
• Slip stitch to join
• Repeat around armholes if you want a cleaner edge

Length Adjustment Option

• If you want a longer vest instead of cropped
• Add extra rounds to the granny squares before assembly
• Or add extra hem rounds at the bottom after assembly

Weaving In Ends

• Use a yarn needle
• Weave ends through the backs of stitches on the inside of the top
• Trim excess carefully

Fit And Customization Notes

• For a smaller fit, stop at fewer rounds and keep armholes slightly smaller
• For a looser fit, add rounds and leave more rows open at the top for armholes
• For a deeper neckline, increase the center neck opening
• For a more closed neckline, reduce the neck opening and join more of the top edge
• Scrap yarn stripes look best when you keep each round a single color

Beginner Notes And Troubleshooting

• If your square is curling, your tension may be tight, go up a hook size
• If corners look wavy, make sure you are doing chain 1 inside the corner and chain 2 between sections
• If the bottom hem flares, use fewer hdc or replace hdc with sc for a tighter edge
• If the neck opening feels tight, undo the shoulder seam a little and widen the neck gap
• If armholes feel small, move markers down to leave more space unjoined
