Here is the pattern that I promised. This pattern came about as a matter of necessity. I purposely have made this sling a little on the deep side so that it will hold any of the standard sized water bottles. If you happen to be needing a sling for a taller bottle, just increase the number of rounds to accommodate the bottle. I also made this bag to be a little larger so that you can put the wider soda bottles in it as well.
The bag works up very quickly. I was able to make a bag from start to finish in about an hour. Once you get the bottom made, the rest of the sling is made on a spiral until you reach the top edging. I strongly suggest using a stitch marker of some type to mark the beginning of each round on the sling as you build up the height. This will help keep it more uniform in height all around.
One note that I want to stress as well is that the strap of the bag can be made a little shorter than you need. The strap will stretch with the weight of the water bottle. The 31 rows of stitching used to make the sling below fits perfectly when hung down straight on my shoulder. For my 9 year old daughter, it fits her perfectly when worn diagonally across her body from her left shoulder to her right hip. To get the measurement needed to fit you or your child, measure from your hip, diagonally up to your should and back down to the same hip. Be sure to start and end the measurement with where you want the top of the sling to be. Subtract 1.5 inches from this measurement to allow for the stretch that will occur when a full bottle of water is in the sling. This measurement should work well in planning the strap length.
The yarn that I used in the same was Red Heart worsted weight yarn in the super saver size skein. One skein should easily make at least 4 of these slings.
Walkabout Water Bottle Sling
By Paula Jones http://simplicitybychoice.com
worsted weight yarn
Crochet hook, size F (3.75mm)
Stitches used: (US stitches given)
ch – chain
sc – single crochet
sl st – slip stitch
dc – double crochet
tr – treble
Treble stitch: wrap yarn around hook twice, slip hook through next stitch and pull yarn through. Yarn over and pull through two loops at a time until you have only one loop remaining on hook to complete the stitch.
This sling is begun with a magic circle. If you choose to not use a magic circle, then simply begin with ch 4 and slip stitch to form a loop, sc 6 times in the loop, catching the yarn end to help secure it in place, sl st to join. Continue pattern as directed beginning with round 1.
Begin with a magic circle. Sc 6 times in loop, join with 1st sc to form circle. Pull thread to close the circle. Do not trim! Leave tail to weave in securely after sling bottom is made before trimming the end. This will prevent the magic circle from opening back up.
Round 1: ch 1, sc in first stitch from ch, sc twice in each remaining stitches, sl st to join (12 sc)
Round 2: ch 1, *sc in next 2 stitches, 2 sc in next stitch* repeat pattern to end, sl st to join (18 sc)
Round 3: ch 1, *sc in next 3 stitches, 2 sc in next stitch* repeat pattern to end, sl st to join (24 sc)
NOTE: From here on, use a marker to show beginning of each round as the pattern works on a spiral.
Round 4: *ch 3, count 3 stitches from chain and sl st*, place stitch marker in this first chain space. Continue the pattern all around to end.
Round 5-18 Repeat round 4, moving marker up each round to show beginning of each round.
Round 19: sl st to first chain space, ch 3 (counts as first dc), 2 dc in chain space, then stitch 3 dc in each chain space all around, sl st to join
Row 1: ch 4 (counts as first tr), 1 tr in each of the next 3 stitches, turn
Rows 2-31: Repeat row 1, use less rows if making sling for a young child. Bag will stretch from weight of the water bottle.
To finish: sc the end of the strap to the sling, centering the strap to opposite side of bag opening. Weave in ends to secure and trim.
