Here is a seamless reusable lunch sack bag. The lunch sack is crocheted from recycled plastic bags. This project is another installment of my to-do list which I am working on. The list is made up of items that I have never made before and I use recycled material to create each item. Once the item is completed, I share it here along with the free crochet pattern so everyone can have an opportunity to make the recycled project too.

This week, I completed my lunch sack which is a seamless bag. I have used this seamless method for quite a while now and wanted to share it here on my blog. You can use it on many different projects when you don’t want to have to sew or weave sides together on your project. It also leaves your item with a nice appearance as you do not have a joining stitch. I have step-by-step pictures of how the seamless bag method works below.

Rnd 24
Repeat rnd 23 by working an increase at both sides of bag.

Flap:
Row 1-5

Row 6
Ch 2, turn. Work one Hdc over the next 2 sts (1 Dec), then Hdc in ea st to last two stitches of row. Work one Hdc (1 Dec) over last two sts of row the same as first Dec of row.

Row 7-11
Repeat row 6 by working 1 Dec at beginning and end of ea row.

Row 12

Flap Edging
With right side facing, attach yarn at top edge of flap. Work one Sc in ea st around outside edge of flap until you reach the first flap corner, then work 2 Sc in flap corner. Continue working one Sc to other flap corner, work 2 Sc in other corner, and finish with one Sc in ea st back up to top edge of flap. FO.

Strap
Create strap by attaching your plarn with a Sc down 3 rows at side of bag, then work a Sc up ea row to top edge of bag. Ch 45. Attach strap to opposite side of purse with a Sc and work down with a Sc in ea st down 2 more rows. (This provides a strong strap attachment.) Turn and work a Sc into bag side next to prior Sc strap attachment sts and back up to the top of strap. Work Sc around the chain until you get back to opposite end of strap handle then work a Sc down next to the last 3 Sc where strap is secured to bag (same as other side.) Adjust your Sc stitches around chain as needed to provide a smooth strap for your bag. The Sc’s slide a bit and this allows for you to adjust your stitches as needed.

Turn and work a Sc in ea st back up the strap until you reach the other end of strap. Attach with a Sc into side edge of bag.

Fasten off and weave ends under on inside of the bag.

Fold in bag at sides to create an expandable side to the lunch sack.
Cut strip of Velcro for flap closure and attach on underside of flap.
