I buy cotton pillow ticking by the yard...I believe its about $4 a yard...I then tear strips 1 1/2 inches wide...I then take a putty knife, smear my lube on both sides, roll up and microwave for about 20-30 seconds...Then they are ready to stick in the patch box or cut at the muzzle or loading block...
I don't trust prelubed patches, they rot on you and burn through destroying your groups...
