Antitheft Backpack Tutorial | RCK Challenge 5, Eri Antitheft Backpack

Monday, March 28th, 2022 is the uploading day of the Rerasan Craft Kuy Challenge 5th. For this session, the theme is an antitheft backpack. Mentored by Eri Tias, the challenge start on March, 5th. For the tutorial, we can watch Eri's video on her channel. you can get the pattern from the video description or just click this link. Print on F4 paper, 100% on the scale. The pattern includes 1 cm seam allowance.

Unfortunately, the marking is written in Bahasa Indonesia only. Hope I could rewrite it in English someday. Or you may just ask her by leaving a comment on her video.

As one of my customers asked me for a backpack for her beautiful ecoprintedeco-printed cotton fabric, an idea came up in my mind. So, I made this antitheft backpack for the customer. And while doing so, I recorded it for my content. 

   

As you can watch on my channel, I remake the video tutorial. I almost make no changes to the pattern etc. But I add some fusible interlining due to the fabric I used. 

Because the cotton fabric is lightweight, I must add some fusible interlining to stabilize it. whether it's on the exterior and lining as well. So, you'll find out I write 2 for each part of the panel, exterior yet lining. Use only medium-weight fusible interlining. In Indonesia, it's called staplek M33 or the lighter one, M10. 

Supplies:

• exterior- I used an eco-printed cotton fabric 
• lining- I used an eco-printed cotton fabric 
• fusible interlining for each panel of exteriors and linings
• super foam for exterior only
• fuse web -->to fuse the exterior and super foam
• webbing 3,8 cm 100 cm (2 pcs) for handle
• webbing 3,8 cm 10 cm (2pcs) for rectangular ring holder
• webbing 3,8 cm 28 cm (1 pc) to cover the ends of the handle --> I used a piece of fabric (28x6 cm)  to avoid over thickness on the part
• webbing 2,5 cm 20 cm (1pc)
• zipper 5 vislon length 51 cm n 20 cm 
• zipper 5 coil 22 cm for the inside pocket
• rectangular ring 2 pcs
• adjustable ring 2 pcs
•  2,5 cm bias tape/ twill tape

Tips for ironing fuse web, keep your fuse web lays neatly between the exterior and super foam. Trim for the excess. 

Tips for using super foam, cut the patterns, not including the seam. 

Or, if you intend to cut it include the seam, zigzag all along the edges to reduce the bulk.

Tips for the handle, if you used a home sewing machine,  avoid using webbing for the cover of handle ends. Use a matching fabric instead of another layer of webbing.

Tips for the handle, you may use matching fabric and super foam or another interfacing instead of webbing. The sandwich technique would do, with the help of bias tape. 

GOODLUCK! SELAMAT HEPI BERKREASI!
