Timapanga mitundu yambiri yazinthu zamtundu wa corten steel garden edge zomwe ndizosavuta kuziyika, zokometsera, zovala komanso zotsika mtengo. Kaya mukufuna kupanga udzu wowoneka bwino, wowongoka wosavuta kuusamalira, kapena mipanda yamaluwa yokhotakhota, mutha kuchita izi mwachangu, mosavuta komanso motsika mtengo pogwiritsa ntchito njira yapansi panthaka ya AHL ndi pamwamba pa chitsulo chachitsulo.

Pogwiritsa ntchito zitsulo zathu zowonongeka, mutha kupanga mabedi okongola a maluwa, malo a udzu, njira zamaluwa ndi mitengo yozungulira yomwe imapirira nthawi yayitali. Mphepete mwa minda yathu yonse yomwe ili ndi nyengo imabwera ndi chitsimikizo cha zaka 10, koma ndikusamalidwa pang'ono ndi chisamaliro, iyenera kukhalabe pamalo abwino kwa nthawi yayitali: mwina zaka 30 kapena 40!
