OK, I'm finally able to think about making my chalk bag without remembering the second occasion I used it ended in hospitalisation! (For the record, I was bouldering and didn't even have my chalk bag on when I fell and knackered my ankle). Anyway, If you want your very own chalk bag from your choice of funky fabric, here's what to do:
Circle 8.5 cm in radius, one of outer fabric and one of fleece
Rectangle 14cm x 48cm just of fleece
two rectangles of 10cm x 12 cm in pocket lining fabric
1 m of lacing (shoelace, corset lace, or anything like it)
2 eyelets large enough for the lacing to go through
One of those things that the laces go through (I have no idea what they are called, look at the pictures and you'll see what I mean.
1m cotton tape and some form of buckle.
Step one is to insert the zipped pocket. It's just big enough for a padlock key and some lip balm.
like when making a bound buttonhole).
This will make the opening lie flat, which mine doesn't. So pretend I did that and in the picture below I'm sewing the triangle to the zip.
Sew each large rectangle into a tube, short sides together. Sew each tube to its matching circle, so you have two bucket shapes, one of fleece and one of outer fabric.
Next take the 14 cm x 48 cm fleece rectangle, fold it in half and mark on the halfway line about 4 cm from each short cut edge. This is where you will place your eyelets - follow the eyelet instructions. Sew the short edges together and then thread the lacing through the eyelets so it lies approximately along the halfway line.
Attach some cotton tape over the seamline so you have something to attach to a tape round your waist, or to a caribiner. Only attach it at the top and bottom, the stitching down the long sides is "decorative" as I used contracting thread (sorry for the blurry picture)
Next you can attach some stiffening to the rim of your bag. I used millinery wire, but you could use zip ties, or not bother if you aren't bothered about the bag holding itself open. I used the zig zag stitch on my machine to secure it, but hand sewing might be easier to control.
I hope you find this useful. If you make your own bag I'd love to see it - e-mail me at firstname.lastname@example.org
Happy climbing, and do be careful (especially on the bouldering wall!)
