wow, thanks everybody for your feedback!
I live in Rome, Italy and I often find fabrics in...something similar to thrift shops, I suppose. The sad thing is that quantities are limited: once a fabric is gone, is gone. Those were sold as multipurpose covers (like, to put on the sofa, on bed, etc) so you couldn't even choose the quantity.
lifetofullest: I didn't used a tutorial for these, but in the past I learned the basics to sew a bag from the Jordy tutorial on this forum. These are simple tote bags, and you can easily follow that tutorial playing around with measures and number of handles to get what you want.
Loobylashes: that's true! thanks for the hint
Crafty girl: they are available on my site, where you can find the prices and other infos; you can find the link on my signature below or under my usericon (I don't know if selling is permitted on this forum, so I won't enter in details here- sorry)
TheEverFalling: they could be totally reversible if I could clearly understand what makes a bag reversible and what not
) I never got it well, haha. I left a hole to reverse the bag, so in the lining there is sewing on that hole, I guess this makes them not reversible, although the sewn part is not so evident. How I can make a bag reversible? sorry for the strange question
