Making a cold frame and where to buy a manger.
Hi, my other half has offered to do some DIY, instigated by a trip to a department store where I wanted to purchase a cold frame. The cold frames available were very flimsy so he came across all manly (!) and has offered to make one for me if I provide him with a specification! Would appreciate any tips anyone has! Should cold frames have a base? Is glass better than perspex? Should the sides be made of brick or wood? Also, can anyone recommend where to purchase a manger / waist high raised bed at all? I've seen one but it's rather pricey. Thanks in advance for any ideas x
