Use the Buckskin:!:Lay all the knives on the rool piece, lightly mark around them and compensate for size and the handles(covers that snap to keep them in the pockets.
Now take extra Buckskin and lay over the knives and cut them so you have a good easy fit after sewing(allow for the hem material).Cut a few long strips for tie straps and carrying handles. Leave enough at the top of the roll to fold over the knives before tying them.
If you can't or don't know how to sew this, take it to a cobbler(shoe repairman) and he can do it for , well, if you brater some BBQ ,maybe nothing. Talk to him and say it can be a down time project(but before Christmas?) and he may just be a good old sole(pun intended).
You could end up with a very inexpensive custom - cover that would be worth at least $500. Send Pron when you get it done.
Curious!!!!!
