Relatively new to "minis"...it took me 20 years to screw up the courage & have the time after receiving a "kit" for Christmas from my mom...completed my 1st 2 years ago, my second this past winter & now working on my 3rd...YAHOOO, I'm so in love with this as a hobby...totally beats TV!!! but my book reading is suffering unless it involves "miniatures"
Anyway, I do digress...1st house wired with tape...yes, finicky to handle those little brads, make sure there are no spilts or bad curves, etc. All was working well, after completing until 1 yr later...kitchen hanging light has gone out, after I broke the bulb trying to unscrew & change it I replaced with brand new light...still not working!?!?! too late to ck tape wire as it is buried under wall paper, etc.
so now the kitchen has no light...groan
Second house was very carefully wired,each new bend or fold & brad insertion was tested along the way, drawing of layout done & filed for future need, completed wallpapering & guess what? ...lighting no longer worked...major double groan & feeling of nausea in stomach!!!!! I did not want to rip out all the wall coverings I had just newly installed... The house is now lit by all LED battery lights....not my favorite but I do appreciate the light.
So, now I have an abundance of lighting fixtures ordered & opened for 2nd project...I have been researching round wire & definitely feel this is the way to go....it actually doesn't appear to be as finicky as the tape wire....will use in a later project, currently have a supply of Battery lites for current (3rd) + a planned future build...looking forward to giving it a go. I follow Brae of Otterine.com & she seems to strictly use round wire...go to her site...beautiful work & she gives gives detailed instructions!
One more thought...I read somewhere that wall coverings could be applied to card stock which would then be placed over the walls, instead of actually applying coverings/paper to the wall itself...then, in an electrical failure you could remove each covered wall section & do some testing/repairs
I hope this helps...so for being so long-winded!....Nan
