PIN FOR LATER Pin for Later MATTRESS STITCH Mattress Stitch Mattress stitch is great for garments or projects that need a sturdy seam, for example, shoulder seams in garments or gifted blankets. If you’re looking for a crochet blanket join that’s hardwearing, simple and strong then this is the one for you. Mattress Stitch Lay 2 pieces wrong sides facing. Insert darning needle through both loops of first stitch from inside to outside of first piece. Insert needle from inside to outside on the corresponding stitch of the second piece. Repeat along working in each stitch. Mattress Stitch You may wish to work through the first and last stitches twice to secure but this is personal preference. Every few inches, lay work flat and pull on seam too secure. Mattress Stitch WHIPSTITCH Whipstitch This crochet blanket join is good for joining seams which do not require to hold weight, for example an infinity scarf. I would only really suggest this for smaller-sized blankets where softness is required, like baby blankets. With wrong sides facing, insert needle from front to back of first stitch working through both thicknesses. Repeat for each stitch. Whipstitch INVISIBLE STITCH Invisible Stitch This is good if you are joining different colour crochet pieces together, because the clue is in the name…it’s invisible! So, if you’ve gone for a beautifully bright rainbow blanket this is the ideal crochet blanket join for you. I would opt for joining using the lightest colour. With wrong sides facing, insert needle from front to back working through back loops ONLY (this will be the two outermost loops as your work is laying together). Repeat for each stitch.
