The idea from Tobias from Wittighausen:
Enclosed I send a drawing for 1 set, but we need possibly 3 different bags.
The material can be a truck tarpaulin or similar robust material. Please ask for suggestions what makes sense.
Quantities are still small… we are just testing and building our shop.
The customer's rating:
We are thrilled. The quality is great, great workmanship and also the drawings are very well interpreted and implemented. The choice of material was exactly right and the functions are also best.
The story of the custom made backpack bags for our products (sets):
Greetings, I am happy to provide an offer for your idea. I have studied the diagrams and I have understood what you are looking for, However If you can please let me know the measurements are in inches or is it 1.9 meters and 0.6 meters? (900 and 1600), this will help to understand what kind of material (strength) I am to find - Either Truck Tarpaulin or Canvas should work well, but the size of the item is also important so that I can work out the meters needed.I look forward to working with you to realize this project.
Thank you very much for your comment. They are measurements in mm! So not inches!
Greetings. Thanks for your quick response. So for now I am going to look it the materials and then we give you suggestions and also pricing. Last year a few shops have closed because of the pandemic effect on business so it is not possible to assume I shall find tarpaulin or canvas at the usual place. So please give me to Saturday to find all options and then will share my ideas and materials and price with you for your comment. Please reply to this message so I can reply on Saturday.
Fine with me. Please also offer alternative materials
I would like one small confirmation what is the exact thickness of the whiteboard? I am trying to confirm the size of the bag again so I make the necessary allowance ?
Hi, please take the following inner dimension 15 cm for 3 idea boards.
Is this sufficient?
Trust well. Sorry I will be a bit slow to respond this week,I have a pressing issue I am looking after. I have found the following three materials for your consideration. One is a black mesh very tough. The other is canvas ( green and safari brown) and the last one is ripstop (beige) material. All these are durable but have different costs. I am also thinking of using African print as trim on the outside of the backpacks to make it unique so I have put two prints for you the handles can be in leather . Kindly advise the material you like so I can give you the price of the materials and then the labour.
Take your time, there is no rush. I need to be sure which material I like better first.
My tendency is canvas but anthracite or black.
I can't imagine black mesh.
Please don't be angry with me if there are no African prints. For this bag I would like it to be very plain.
What is the cheapest material?
Thanks for your efforts
How are you? Thank you very much for your patience. I have to say that canvas is either army green or beige. And for canvas there are two types and prices are as follows. Canvas medium(CC3 ) 8 Euros per metre, heavy (CC4) 10.3 Euros per metre. For each bag we shall need 4 metres per bag. Then of course other items such as leather for the handles, sponge and lining.zips.
, Magnetic buttons and findings.
The other material I had proposed Meshnet is 7 euros per metre and ripstop is 13 euros per metre and is the strongest one.
Let me know.
I think we should try The Canvas means CC3. Then we can see if it is strong enough. Please use Arrmee green.
If you could protect the bottom a little bit at the corners that would be good. Because I think you put it on the edges and they should be a bit stiffer and more protected. There you can take something more robust. I am very curious.
Do you have any questions?
Something else: you should absolutely 20-25 kg with the belts can carry. so please also pay attention.
Greetings, thank you for your message. I have put together the costs for ONE bag only so that we make one and then from there we can make the second one. I hope that is acceptable?
The materials we shall now need is as follows:
1. Canvas CC3 - 24 Euros
2. Zips - 1.7 euros heavy duty
3. Sliders - 0.5 euros
4. Lining - 12 euros ( 4 metres)
5. Leather for sides, bottom and top of handle - 15 euros
6. Strapping- 1.9 euros
7. Soft board- 0.9 euros
8. Magnetic buttons, D rings - 1.9 euros
9. Labour - 60 euros (almost 3 days work)
I have decided to break it down this way so the cost is understood
So if this is okay we can proceed.
Let me know
Greetings, on the above submission one mistake - the cost for the zips is 9 euros. Other the breakdown above remains.
Greetings, I have noted the weight of 20-25kgs and have given the offer for one bag below.
Thanks, I need a few more days as I have other projects.... please be patient a little longer. We will do this for sure.
This is noted. Thanks
Hi Fatma, enclosed small change. See new picture.
The bag has become easier now... Has no overlap and instead a zipper at the top.
Side pockets can be held very easily.
Greetings, I have noted your comments.
I shall commence next week and share with you images
I'm looking forward to...
How are you? I have finished the prototype and have seen the areas where I should make some adjustment. For example the bottom we shall use micro padding and put stands at the bottom of the bag. (Not leather as suggested earlier) Also given the size of the bag I am thinking of changing the straps. I put one long one over the bag but use straps like for handbags on the sides. This may give it some stability.
I shall share finished product Tuesday or Wednesday ready for shipment.
Thanks for the pics and your helpers 😉 It almost looks like the men caught a fish.
I like your changes or adjustments very much.
Remember that you can carry 15 kg on the right or left shoulder well balanced.
Looking forward to seeing the product.
Please take another picture of you and the bag....
Greetings I trust well. I have really tried to take photos of the bag but it’s too long so not getting good photos. However it is finished and now ready to be sent. Thanks
Thank you and I look forward to seeing the results. Tobias
