Where to buy rose covers or make some? Martin, Cleethorpes

Martin, rose covers are not sold any longer, but you can make some using plastic beer mugs (one pint beer mugs, the type you get at fates). You have a leather punch, the one that punched holes in your leather belt. Punch 3 holes around the rim, thread a thin stiff wire through the holes and clench the wire over, then bend about a foot of wire down and put it through a wooden cloths peg and bend it over.  You can now place the upturned mug over the bud and peg the wire to the stem about a foot down. Check them after a week in case the neck lengthens and the bud touches the top of the mug. Reposition if necessary. Kind Regards, Doctor Rose
