Just in case you missed it, a couple of weeks ago, I posted the pattern for my Blog Collection Round Hobo Bag, possibly my favorite bag so far. Although that Windmill bag... Maybe I should just refrain from playing favorites.
Anyhow, because the straps of the bags in this collection are meant to be interchangeable, I chose not to post it all in one go. That, and I had yet to write up a coherent pattern.
Please be aware that the instructions for the strap are specific to the Round Hobo Bag, but a quick note about changing it up for other bags follows the pattern.
Single Shoulder Strap
chain 120, do not turn, skip next 54 sts
Design Note: For now, ignore those 54 skipped stitches, but you may want to mark the first and last skipped stitch so they're easier to find later.
Round 1: being careful not to twist chain, connect to next st w/sc, sc in next 53 sts, sc in each ch across (174 sts)
Round 2: sc in each of next 53 sts, skip next st, sc in each of next 119 sts, skip last st (172 sts)
Round 3: skip 1st st, sc in next 51 sts, skip next 2 sts, sc in each of next 117 sts, skip last st (168 sts)
Round 4: skip 1st st, sc in next 49 sts, skip next 2 sts, sc in next 115 sts, skip last st (164 sts)
Round 5: skip 1st st, sk in next 47 sts, skip next 2 sts, sc in next 114 sts, join w/sl st in 1st st (161 sts)
finish off, weave in ends
(opposite side) Round 1: connect w/sc at 1st skipped st, sc in next 53 sts, sc in each unused loop of ch (174 sts)
Rounds 2-5: repeat Rounds 2-5 above
finish off, weave in all ends
Modifying this strap to fit any bag is fairly simple. Instead of skipping 54 stitches, use the stitch count of the last row/round of your bag. Divide your total stitch count by two. This is the number of stitches you will skip.
In the coming months, as I post other bags from this series, I will also post the how-to's for their respective straps including a slightly narrower shoulder strap and a much shorter rolled handle. In the meantime, have fun playing with this one.
