Ma ny fabric use nhi kia, foamic sheet per banaya hy but agar apko fabric use krna hy to thick fabric lain like KHADDAR (soft quality) takay lambay arsay tk chalay.
Agar exam ma likhna hy to search on Google ma bht exact nhi bata paongi kion k bht time hogaya course kiye hoey. Phir bhi yeh kuch meray demagh ma araha hy: 1- They are miniatures of the real objects. 2- They are designed according to the hands of children so they can handle them. 3- They give children a real life experience as if they are working just like their elders. 4- They teach everyday lifeskills to kids. 5- They are attractive. 6- Most of the material is didactic which means it has a self control of error. Hope this helps laikin phir bhi Google per search zaror karlain.
